I've never flashed a phone to a different CDMA provider so I thought I'd ask here first and see if anyone had knowledge of how to do this? Or point me in the right direction to somewhere to learn how to? I've unlocked the GSM radio for use on att already and I'm sure it's a similar procedure, but I followed a guide to do this and have little experience with it. Thanks in advance to anyone that has information on this.

Also, how did you go about unlocking your phone? If you unlocked the gsm attenna. I assume that the phone is fully unlocked and you should just be able to switch it over. As long as it isn't on another account I.e. Verizon.

The CDMA providers blacklist phones from being used on other CDMA providers networks. "Flashing" in this sense is stealing and ESN/IMEI from an existing phone and cloning it to your phone. Not only is it extremely risky for your hardware, it is extremely against the law and cannot be discussed on these forums.
Certain phones like the Rezound and the Dinc4G have additional feature of GSM radios added for compatibility with oversea networks, you aren't really flashing anything so much as the phone reconfigures itself for GSM or CDMA depending on what kind of SIM card it finds.

Umm. Not true at all actually. I had a P+ dealer switch over my phone with a bad esn (mother in law didnt pah her bill) and they didn't use a "friend" phone. It doesn't require stealing a phones imei or anything it requires a lot of work to port it to a different carrier, but doesn't require anything illegal. Not to mention what you're talking about is also based on the staye you are in. In the states it js legal as long as you aren't copying two have two phones on one service and is completely legal ( state dependant) if you own both phones. Check your facts.

as far as using it on gsm networks, yeah its possible you just need to either do some things (I could dig up a link if you want) on stock and have it kinda work, or find a rom that supports it and flash that (recommended, what i'm gonna be doing). and flashing phones to other networks i am pretty sure is illegal, i know from experience, i tried to work that out on xda and they sent me away saying this isnt a topic allowed of these forums, so if you still want to know about carrier flashing i suggest another forum
but anyways just making sure i am following you right, you want to gsm unlock but want to use it on virgin mobile (a CDMA network?)

It should be possible, I've gotten as far as getting the NV values on both radios, but it seems as the 9k wants to search for signal on 800mhz only, at least according to DFS.
The Thunderbolt is able to get 3g working on Boost/VM/etc. at least from what I've seen. Considering the similarity between it and the Rezound I was hoping it would be easier...

Flashing phones to different networks aren't illegal. It is a state dependant thing. I went and had my note 2 flashed over at a business in the middle of a bestbuy, guitar center, more big businesses. (Aka, big businesses near ~ not a shady place)
Yes, I know that Virgin Mobile is CDMA. I wanted to know how to unlock the GSM antenna purely for education purposes.

It is easy, but only to people that already know how to do it. The process is similar for most phones and doesn't require a lot, but most that try to do it dont know what they're doing and it takes them forever. What we need is a good electrical engineer.

Quick update:
The Rezound can work on Sprint-based towers, at least with leaked global (4.03) and stock global (4.05) radios. It took me couple of days of fidding via DFS, but right now I do have 3G working, albeit with the stock ROM complaining that mobile data isn't working. Trying out couple of ROMs to see which ones is usable.
Most important thing is that the 8K radio needs to be set to NV_ONLY but that 9K can be set to RUIM preferred. Also, flashing the firmware (from the recent 4.05 global update) will reset the 8K radio to RUIM, which is a good thing/bad thing. Good thing is that if you ever want to NV reset (since hard resets do not seem to wipe NV), flashing the latest firmware/radio should get you back to RUIM/stock PRL/blanked #. Bad thing is you need to fiddle with some of the settings in DFS again, but at least it's only for the 8K radio so far.
Another thing that probably made it work was to use the same PRL from the phone Sprint thinks you are using. For me this was the 61009 PRL. Profile info only needs to get stuck into the 9K radio and I don't think you really need to bother with the NAM2 stuff. But again, I've done too many fiddling to be able to say for certain.

I can't seem to find an up-to-date tutorial on performing this process. I found some from mid-2009, but people are commenting that *228 doesn't work, this thing doesn't work anymore, that thing doesn't work anymore. Has anyone done this process recently?
I am trying to get this phone onto Verizon without a data plan since I will just be using wifi.
As far as I know, Sprint phones are GSM, VrzWls are CDMA. Totaly different frequencies. It is impossable (without an enginering degree and a lot of solder) to make one work on the others towers.

There are a lot of people on these forums that have done it - I just can't find concise up-to-date directions.
have you tried loading a verizon prl on the phone? i have my sprint tp on pageplus, which is a verizon mvno, and it wouldn't program ota until i loaded the prl.
I have not tried loading anything yet. I am still looking for directions that are not from 2008. Also, I have no interest in custom roms at this point. I simply want the Sprint phone to work on the Verizon with the least amount of work.

Step 1. Grab your phone and take it to a Verizon store to have it activated on their network...

There are other things that you can do manually, but since the only thing you are interested in is to have the phone working for a different carrier, then that is all you need to do.

I was wondering if anyone knows how to put straight talk on a cdma android phone. Preferably a Droid Eris. Please any knowledge? Let this be a general question.
Not possible. Go to Howardforums.com and check out the straight talk forums. You need to use a straight talk phone. You might want to check out page plus cellular, they offer bring your own device on verizons network.

Wrong. Your information is out of date pko. Boost was bought out by Sprint a while back and uses both IDEN and CDMA. The CDMA part is now the actual Sprint network so from what I have heard on various other forums you can get any Sprint phone and run it on Sprint prepaid (Boost). They have an unlimited everything plan for $60/mo. Or better yet you can get a Sprint 450 minute plan for less and get unlimited texting and data I believe.
Well now I've got boost with full evdo network. Not 1xevdo full evdo. Anyone that wants to know how I did it I will tell you if I see a request I am tired of uptight people hiding and keeping secret thing that people wanna know.

You need a ST donor phone, yeah, but you should never turn it on or activate it, just need it for the MEID. if you already activated it you're SOL, need a new donor.
For Anyone who cares
Let me start off with saying, I have been screwed over by VZW far too many times to allow them to continue pliaging my pockets. I'm currently working on converting my Verizon (CDMA) Smart phones (HTC Incredible; 1st Gen Android; iPhone 4) over to straight talk.
Now for all you nay sayers, who, for the longest time have made claims that it can not be done; well I tell you it can. I know it's a cliche, but as people have said before, "where there's a will, there is a way!"
This will involve a very intimate understanding of all the mobile networks there are, and, the different networks Straight Talk uses. For anyone who is currently pondering the question "Can I flash/spoof, or otherwise get an AT&T phone on a CDMA network?" The answer is and always will be NO! This will never change. The only exception to the rule is the iPhone4s. This is due in part, to the fact the iPhone 4s was originally designed to be a world phone. This means that the iPhone 4s has the capabilities to switch to CDMA from GSM and vice versa.
If Straight Talk does have a white list of ESNs that have acess to the network, then that would be a tiny problem. I say tiny problem because it can be overcome. This comes down to legalities though. In order to get any CDMA phone (to include verizon phones) onto the straight talk network, you will first have to buy a Straight Talk (CDMA) smart phone. Next you'll have to unlock your current Verizon phone (or any other CDMA network phone, i.e. Sprint, Boost, etc.) from the current carrier. Then you'll need to spoof your IMEI and ESN to what ever your current Straight Talk phone's IMEI/ESN is. You should be able to find some software to assist with this, by doing a google search (specific site will follow in my next thread.
Spoofing both the IMEI and ESN are very important, as the ESN is unique to the IMEI. Essentially, you are fooling the network into thinking that the phone accessing the network is the one you bought from Straight Talk. Another reason for this is so that VZW never catches the on to what you're doing, considering they monitor the data usage of each phone on thier network. If they notice an IMEI from the phone previously on thier network, now with a new carrier who offers cheaper services, they will cut and block you from their network.
(The following thread is a concept in progress. If anyone else thinks they have another/easier way to do it, please feel free to comment)
All questions are welcome, however, if you lack a basic understanding of the cellular technology or the information flow through the mobile networks, I will probably ignore your question. (SO GOOGLE IT!)

GSM phones
I know this is old but just reading around thought id post, i just bought an atrix 2 online an at/t phone and got straight talk last week, and all you need is a GSM phone on bands 850 and 1900 mhz thru T-mobile at/t or unlocked and your good, they dont do cdma because it gets complicated if you use anyhing then the phones they sell. But i can report on my "4g'' phone which is HSPA+ i get 8mbp/s up and 2 mbp/s down in my area, so great service!
i'd suggest page plus - its also on the verizon network... nothing special needed, just a clean esn eris - call pageplus and they'll activate you for free, free $2 to get you started and then all you do is buy pins to refill service.
also, you can load cricket prl and some more to get cricket working...

So I put the latest .10 ICS leak on my phone yesterday because I can't wait for the OTA since i'm leaving soon. I downloaded the 4G on off app and am thinking I should be able to pop in any SIM card and it should work on GSM. Is the phone unlocked? Also I might need to use my normal Verizon SIM to use in Italy and Spain. The verizon reps said if I left it in it would work just fine. Is this true? I currently don't have any GSM cards to test with and I've been looking everywhere for the answer but no success. Help would be amazing.
Thanks in advance

With GB or the ICS leak you probably can get basic calling and texts with a GSM cell company sim card.
With the conrom ROM you should also get mms and data to work. Supposedly everything works.
Also, I suspect gsm antenna is not in the extended battery cover, so you should use the standard back cover that came with the phone.
I personally have not tried gsm in my rezound, so the above advise might be incorrect. this is just something I am interested in.
howard
p.s. T-Mobile sells a $1 sim card with 10 minutes of talk time, an internet deal. So you can buy this $1 simm to test with.
p.p.s. You will also need to go into the settings and add the apn settings for the cell company whose sim you are using. data and mms won't work without this.

Thank you so much. I just need calling and data and mms to work. I'm just going to google how to change the APN setting as you said. Thanks a lot for the help man. I have the ICS leak which is supposed to support global roaming straight from VZW.
Well, there is a thanks button you can click on.
I do not know much about Verizon's New global roaming, bit I suspect it will be expensive per minute. Using a local cell company's sim card probably will cost less for long visits overseas.
I wrote an app called HZUTILS which can also do the radio changes like the LTE on off app. My app is free, also does a few other functions, and if you click on an advertisement I earn a few cents.
The CONROM is available in the development forum. During installation one is asked GSM or LTE. no easy switching back and forth. I suggest you make a nandroid backup first with Ramon ra recovery or the touch recovery. Restoring the backup is a method for returning to LTE. Or one can reinstall the conrom and select LTE.
If you look through the development forum you will find other gsm ROMs. The CONROM does both LTE and GSM, was made from the latest .10 ICS leak, and sounds like it is very reliable.
p.s. let me know how this works for you.
Thank you but I don't wanna root my phone really.. I forgot something last time and almost bricked it. Well not really but it was scary. My only question is really can I just switch it from your app as it is now because I can or must I have a custom Rom for some type of reason?

I recall, a few months ago, reading a very long multiple page posting about people having various levels of success with stock GB and changing the radio setting using LTE on off app. People were successful with phone calls and texting, but had difficulties with mms and data.
People did strange things to get data working, and it only worked for some people. I think it involved driving the phone in a car to get somewhere with no cell signal, then back home? Not sure, as I don't recall it very well.
Then people started typing in the APN for their gsm provider. This evening, just for fun I tried typing in the APN for T-Mobile into .10 ICS leak rezound, and it would not get saved. No error message. Verizon appears to have locked out the capability to add a non Verizon APN. So, yes, I think a gsm ROM is needed.
BTW, there must be plenty of rezound owners using GSM who can more confidently give you more concrete advise. They can tell you what they tried, what worked, what didn't, and what is the best approach. I think the answer is a GSM ROM, or paying high roaming charges to Verizon.
Alright ill just try and get a sim off someone on at&t and see what happens. But thanks a lot man I hope I get an answer from someone doing it. You were a lot of help ill let you know how it goes!!

I just received the official Verizon ICS in the last hour. I am poking around looking for the global feature, since it is THE promised reason I bought the phone. Offhand, I do not see the global feature anywhere . Network mode still only shows' LTE/CDMA' or 'CDMA only' as the choices, so it seems that 'global' is still not official from Verizon in the ICS as just shipped.
The LTE ON/OFF app seems to have a few more options than when I last looked, but I've no idea what's may have changed.
I put in a tmobile SIM card and changed the settings in the app to GSM and wcdma and it worked calling and texting! It didn't have data but if you go to mobile network settings and access point names I feel like you could add the apn and be golden using data and mms over gsm. I'm Hoping this is the truth but I don't have anything to test it with

that option to show network modes when dailing *#*#4636#*#* is removed in latest RUUs and official OTA, but however you may flash any of ROMs available to get GSM

So SMS worked with the ICS OTA, both send and receive? Last time I tried 2 months ago under Gingerbread, GSM calls were fine, but could only receive SMS text, could not sent texts, and never got data to work.
I've spent over 1/2 of the last 3 months overseas, so this is a big deal to me. Even if just the calls and SMS send/receive work, I will be pleased. VZ told me the global feature is not in this latest Verizon ICS OTA, but maybe the inner workings are there and they just haven't put in the frontend and any VZ profitmaking carrier lockouts?
I am off to South Africa next Friday. Sounds like I will have to get an MTN sim in ZA and try again when I get there. Maybe this ICS OTA will have some value to me afterall. I'll try to remember to post back here, whether it works or not. If it all works, however, I'm pretty sure the posting will only be redundant info, since my screams of giddiness would be heard around the world... afterall, I've been using an old unlocked GSM RAZR flip phone when I travel.

I'm a noob here, but other places i'm not. I have read VERY many posts and the gist of owning a thunderbolt is that it only work(ed) on CDMA VZ so it is not compatible with GSM although it has a SIM card because its is/was locked to VZ only frequencies.
Just to make sure, I called VZ to attempt to get an unlock code saying I was going on a trip overseas and needed my phone to work. I was told that if I upgraded via the OTA to ICS, my device would then be compatible with GSM and I could simply use any SIM card in my phone and get it to work.
What I am trying to do is move over to straightalk away from VZ.
Instead of unrooting, I flashed the radios and ROM available on this site and ICS is up and running.
So has anyone tried straight talk yet on ICS?
That doesn't sound right to me but I would be interested in finding out whether or not it works. From what I understood about the antenna in this phone is that it is locked in on the 700mhz band at a hardware level. Also there are no settings to change to GSM in the network settings.

Hmmm. Don't know why tech support would lie though -- especially when I waited online for about 30 minutes throughout the conversation. I've been a customer since 1997. He even said, after I switched to ICS, simply insert new SIM and I'm ready to go.

They may not be lying but rather don't know what they are talking about lol. They are wrong all the time. Just because we have a sim doesn't mean that putting a gsm sim in makes it possible to use on other networks. Give it a try maybe they finally did make it possible. Like I said I thought at a hardware level this phone was permitted from using gsm bands.

RE: Thunderbolt to straight talk
Granted, they may be wrong. But, all the many hours of reading I have done, says that CDMA only phones don't have SIM cards and my TB does. And per another posts GSM in the USA operates on more frequencies than abroad. Why would HTC create a phone with a SIM card if there was no reason because it was only CDMA?
Regardless, I purchased a ST SIM and an unlimited plan to try out. I'll post back after I see if I wasted my $$$ or not.
The LTE frequency Verizon uses is actually a GSM which is one reason. Verizon owns the upper c block of the 700mhz spectrum. Also, because Verizon is originally a CDMA carrier they had to use another antenna in all LTE phones in order for them to function. The LTE antenna uses data only. It is not equipped to make phone calls unless a phone call is already in progress in which case the phone is routed through the LTE antenna and is then made over the data connection much like VoIP.

disconnecktie is right, the Thunderbolt can not connect to GSM services. The sim card is not a GSM sim card, its is a 4g LTE sim card. Just because its called a sim and looks similar, does not mean they are the same. The guy you spoke with on the phone probably knew nothing about the Thunderbolt and just assumed that because it has a sim card it would connect to GSM networks.
understandably.

"The LTE antenna uses data only. It is not equipped to make phone calls unless a phone call is already in progress in which case the phone is routed through the LTE antenna and is then made over the data connection much like VoIP."
So theoretically, if there is an LTE only antenna....how does a call get routed regularly when LTE networks (such as 1G and 3G) occur when LTE network isn't available to pass the information over the data connection? More than one antenna?
I'm not expecting this card to work in and of itself. I'm going to swap out another GSM to see if after ICS upgrade, it is actually opened as promised. Now if it doesn't have the requisite antenna, that's understandable, but in that case, why theoretically couldn't I just get a GSM antenna and swap it out for the CDMA one? Can't be any worse than replacing a wireless card in a laptop?
Based upon the "answer" given to me by VZ tech support, I have to wonder if there really is a different antenna or simply the "sim" card installed locks it into the frequency -- and the OS lock(ed) into the sim card previously. A SIm card is essentially what allows you to communicate with a carrier afterall.
Definitely interested if this works, thanks for attempting this

All the LTE sim does is authenticate your phone on the network. That is the reason *228 is no longer needed.

The thunderbolt does not support GSM. It has 3 radios, two 3g cdma which enables svdo or simultaneously voice and data over 3g. FYI some new 4g phones won't do this. The LTE is data only and no phone calls are placed over LTE on any phone for vzw. VZW is not setup for voip yet and that won't start until at least 2014. The thunderbolt is not global ready even with ics. There is no apn info to edit. This all has been discussed many times over the last two years.

Just to clarify I wasn't saying the thunderbolt uses VoIP but that svdo is similar is all.

I'm no cell tech and I get what you were trying to say. I apologize the last part of my post was a little rude. I don’t think voip and svdo are even close, I admit I could be wrong. Voip uses a data connection to place calls while svdo uses the cellular connection for calls and data. If you place the phone into airplane mode, connect to wifi you would not be able to place a call. If you had voip you'd be able to place a call. I know many carriers offer some sort of 3g to network extender that creates a similar type of connection.
Sent from my SCH-I605 using Tapatalk 2
Svdo also makes it so that calls can be placed over 4g when it is present which is like VoIP. Either way I know it isn't exactly the same but was merely using VoIP for a comparison.

In my original post above I incorrectly used VoIP when I should have used VoLTE, I knew what i wanted to say, but used the wrong terms which can lead to confusion and this is all to the best of my understanding
The Thunderbolt as with all 3G cell phones make phones calls over 1x voice network while data is handled by 3G network. The thunderbolt does not make any phone calls over 3G or LTE, it has multiple radios which allow SVDO, a 1x for voice calls, a 3G radio, and a LTE radio. Calls are placed over 1x and data is handled by 3G or LTE whichever is available.
The link below has a good discussion and more clarification on the Thunderbolt when it was first released.

I realize that it has been "talked" about. But based upon conversations with VZ support perhaps it was time to rehash it based upon what I was told.
As far as the APN to edit -- after ICS update (non over the air -- the one provided here). See screenshot. There is even a folder created on the SD called APN Backup restore.
My phone is rooted using revolutionary and running the ICS deodexed, etc. found on xda-developers.
Based upon what I was told by VZ tech support, I purchased a ST test SIM with unlimited service. I installed it today and get SIM card is from an unknown source. I googled that and it appears to be locked. I thought I was unlocked and rooted using revolutionary. But now I question that. So am I truly unlocked like I thought I was? I then tried getting the unlock code using fastboot as per instructions on HTC's development site using oem get_identifier_token waiting for device, and I get stuck at "waiting for device" with no information ever coming up. The only way I appear to be able to communicate w device using ADB is by letting the phone boot then connecting it via usb using debugging mode, and always awake, then it appears as a device, but that's where I get that waiting for device message.
Meanwhile, with the ST card in it's downloading email. I just cannot send.

Your phone is S-off, and rooted, unlocked is totally different. Unlocked means that verizon has allowed that phone to be used on other networks and carriers. You should really do some research, you will find that the thunderbolt will somewhat work on straight talk for a little while, then they will kick you off the network. Just google it instead of questioning everything people say here as they are just trying to help you and you seem to want to do nothing but argue anything that is said.

First off, I'm not trying to "argue" with anyone. If these forums are not to ask questions, then what are they for? With that said, as I previously stated, I have spent HOURS which have amounted to DAYS reading not only the forums here and elsewhere and the information conflicts -- and I may have updated information who the heck knows. You never know when there is false information out there floating around and when it becomes outdated -- and the only way to update that information is by sharing upon these types of forums, I would think. You take your car to an automechanic and he tells you the entire transmission needs to be changed, do you just say ok or do you ask questions until you can fully understand the scope, do you do research, and if that research conflicts, do you ask for a second opinion or simply tell him, ok, go ahead and change it?
Milimbar said:

And as far as unlocked by Verizon, I followed a post until I reached an HTC forum indicating it can be unlocked for all carriers....by replacing the carrier OEM identifier token with an unlock code in binary format from HTC. See what I have pritned and attached.

I think your issue is you read too much into this. Yes, your phone cane be unlocked, it can run on other carriers and networks.
Your phone can however only use CDMA carriers and networks. Just because it can be unlocked does not mean it can be used on networks that do not support the hardware your phone was made with. nothing can be done with software to change that.
Your second problem is, you are misunderstanding terms, and HTC them self are not helping this. The PDF files you linked say unlocking, they refer to unlocking the bootloader, meaning you gain S-off (you can flash files) The unlocking you are questioning here is to get your phone working on another network.
Those 2 things are entirely different.
A phone is designed to work on specific frequencies when it is designed. Some phones are CDMA phones, some are GSM phones, and some are global (they use both). This is a hardware thing. Nothing changes this once the phone has been made. Our Thunderbolts are CDMA phones, unfortunately we can not just up and go to AT&T or anywhere we want with this phone.
I am sorry for being argumentative with my last post, you are right this is a place to discuss issues like this.
If you search for StraightTalk you'll find that it may be both CDMA and GSM supported depending on where you live. If you search for Thunderbolt other carrier you'll find that some people have had limited success with missing functions getting it to work on other carriers.
If Your switching to another carrier, buy a phone for that carrier or a global phone. It's a lot of work getting a phone to work on another carrier and you can get a smartphone better than your thunderbolt for a low price on a MNVO. If your dead serous on taking your thunderbolt to another carrier it loks like Page plus is going to be your best bet. USE EXTREME CAUTION when flashing your phone as you could brick it and it would do you no good at all.
Hi guys,
I spent a lot of time trying to do this and would like to share my SUCCESSFUL efforts with you all!
First let me clarify some of the terminology. Sprint and other carriers program their hardware EPROM to their network specs and lock access to it. This lock is called the MSL code!!! [Master Software Lock?? ]. You would need this code if you want to make any changes to it.
Electronically Programmable Non Volatile (ie a fixed value chip)ROM which is also called NV Rom (NV in short) is where the carrier customization are stored and read from when the phone boots up. The unlock process changes the carrier data to be read from a SIM card instead of from programmed NV. Also note that CDMA or GSM SIMs are actually called RUIMs in the tech world (<--Wiki this). Something I learnt the hard way...
Second, this is not rom flashing (i.e putting another OS on your phone's SSD card and updating the boot records). You will be programming the phone and if you mess up mommy wouldn't be able to help you . There would be noway to unbrick your phone so check your USB cable (most common culprit) virus scanners running on your PC etc etc.. before you try this.
Please thank Vinod Nayak at Rimweb for putting this all together for us. I am in Tokyo and have followed these guides to successfully unlock my Sprint LS990 to work on AU by KDDI (albeit only with 3G speed). So if you are still reading get a cup of coffee and head on to the sites below and read on. Please note you may need to register on their forum to see the screen caps (recommended).
You need the MSL code to reprogram your phone. Follow this guide to obtain it first and keep handy.

So, this will allow me to take my Sprint LS990 to Verizon?
If you get a sim/ruim from VZ I think you should me able to. Try it and share your experience.....
If I do this will my Sprint service stop working until I change back to NV_Only?
You can select RUIM Preffered setting instead of ruim only. That should allow the phone to default back when a ruim is not present in the slot. This is what I actually did.

This seems to be the closest thing we have to a proper carrier unlock, especially if the RUIM preferred option sticks and allows continued function on Sprint (if desired). There's a thread in another form (can't remember where) that has a method for unlocking all the phones radio bands. These 2 things combined could make a true world phone, increasing the dollar value and function.
I jacked around with DFS on my old LGOG with an embedded SIM and no bootloops, although RUIM preferred wouldn't stick, it gave me a chance to look around. Has anyone successfully unlocked their G3 to use a SIM or any CDMA carrier with this method?
I'm not ready to pull the trigger on it but am thinking about picking up a used G2 to mess around with and see what I can do.

I don't know about that. I think you're looking for a corporate PRL which allows faster speeds when roaming. I'm looking for someone who is in the US and still on Sprint but tested the RUIM preferred method with other SIMs and back to Sprint domestically to see if it works forward and backwards.

I'm wanting to try this with Ting (since it's BYOD blacklisted until August), but I'm curious about the "only 3G" issue the OP had. It wouldn't be so bad, but it would be nice to be able to revert back once August rolls around to get on the 4G. So my question is:
- Does this process change things that can be backed up / undone? (I'm guessing not, but would love to be wrong)
Incidentally, Ting is rolling out GSM support as we speak, so I may try to go that route first, though I think I might only get Edge speeds...

3G issues (LTE not working) might have something to do with the bands. Unlocking more radio bands on the qual comm is another process that is documented in other forums. Very detailed and you don't want to mess up.
