I know the Jetstream was designed to be run on AT&T and Rogers, but I am curious if it is possible to flash a radio to enable usage of T-Mobile's HSPA network, much like the Samsung Galaxy Note has been enabled to, as seen here.
Can any of the amazing Devs out there shed some light on this?

jdavis08, Simple answer is yes. It is a standard 2G / 3G / LTE (AT&T / AWS band) phone. So you can use it on ANY 2G / 3G / LTE network with a SIM. But you may need to break the SIM Lock on any handset.
Just wanted to clarify. The Jetstream is 2G/3G/LTE /capable, 2G (GSM): 850/900/1800/1900MHz, 3G (UMTS/HSPA): 850/1900/2100, and LTE: 700mhz & AWS-1700/2100.
Currently, T-Mobile only uses the AWS for their HSPA+ network, not LTE (from what I understand, AWS will be transitioned for LTE and 1900mhz refarmed for 3G/4G early 2013) - and if I'm not mistaken, the HSPA+ is only supported by the "3G" band of this device, not the "LTE"
So - to make a long story short. I am a T-Mobile subscriber with various "4G" phones from T-Mobile. Their 4G only works if the phone has a radio with AWS for HSPA as T-Mobile (unlike AT&T) does not use the 1900mhz for their HSPA (yet). I own this tablet.. It has been SIM unlocked and it simply does not get anything above EDGE... and I live near and visit major cities in Washington State, Seattle/Bellevue/Tacoma, which definitely have TMo's 4G coverage.
I know I should just cool my jets until TMo rolls out the network upgrades, as I have no interest in joining AT&T. I was just curious if there was some way to "trick" the phone to use the AWS frequencies for HSPA, like the Galaxy Note has been made to do as the radio specs are identical.
I know that the Note was enabled to do this by flashing another radio. Support is minimal for the Jetstream these days... so I was just reaching out.
Thanks guys

Hey guys, I just got my new HTC hero. I'm with AT&T now and having the unlimited 3G data plan. I setup the configurations of APN settings as following:
Access point: wap.cingular
Username: [email protected]
Password: CINGULAR1
But I only see an "E" at the connection status which I believe indicates EDGE. Can anyone tell me how to get 3G work on this device?
Thanks a lot!!!
I didn't realise the hero was out in the us yet but if it is i don't know why and if it isn't out its because i don't think it surpports american 3g networks i think you can only get 2g.
Yes I got this phone out of the US.
So you mean there's no way at all to get 3G to work on this phone with AT&T or any other carriers?
In its current state the phone does not support the AT&T bands for 3g.
There are rumors of an AT&T version coming October 11th, that would support 3g.
European/Asian version of this phone does not work with US 3G. AT&T's 3G network requires the bands 850 & 1900, while T-mobile's 3G requires the bands 1700 & 2100. European/Asian version supports only the bands 900 & 2100.
Does this mean T-mobile 3G may work on this phone?
T-Mob's 3g should connect to this phone, if you could find a signal, haha.
http://www.androidauthority.com/index.php/2009/07/03/htc-hero-approved-by-the-fcc-with-att-3g/
Neither T-Mobile US nor AT&T will work with this phone for 3G. The only version of this phone that exists at the moment supports ONLY European 3G. There are rumors of the device coming to AT&T, but nothing confirmed. IF that happens, the new phones would work, but that wouldn't change the fact that the device you have will still only function on Edge.
Sorry to be the bearer of bad news, but it's true.
It's actually Sprint pal. Also, there was a picture for Tmobile also (this appears to be a rumor).
T-Mob uses the 2100 spectrum so i dont see why it wouldnt work.
And a CDMA and a GSM (With AT&T 3g bands) has gone through the FCC recently.

No, it won't work with t-mobile USA's 3G network.
Yes, T-mobile in Europe use the 2100 band for 3G so the Hero works. But T-mobile USA use 1700 and 2100 bands for 3G, and you need a phone that support BOTH bands to connect to its 3G network.
Unfortunately, unless T-mobile USA decides to carry this phone (and they have already said that they wouldn't), there won't be a version of Hero that support its 3G network. This is because T-mobile USA is the only carrier in the world that uses the 1700 band for 3G. You may ask why T-mobile uses different bands for 3G in different countries. This is more of a regulatory decision than a business decision. If you are interested, go read about those FCC spectrum auctions.
All in all, European/Asian version of the Hero won't work with any 3G network in the US. The product id of the European/Asian Hero is HERO100, it supports only the bands 900 and 2100 for 3G. There will be a North American version with product id HERO130 that supports the bands 850 and 1900. It will be released either on AT&T or on the Canadian carrier Rogers, because only these two carriers use these bands for 3G. Currently it is not know whether it will be on AT&T or Rogers, but that latter is more likely IMO. Finally, there will be a CDMA version, with product id HERO200, for Sprint. This is more or less confirmed to be coming in October.
T-mobile US 3G uses 1700 for down and 2100 mhz for uplink. So 2100 alone isn't enough as you need both directions to connect.

Thanks! That was very informative, although it totally crushed my dreams of owning a Hero while remaining on the T-Mobile network.
This may be stupid, but I can't find the answer in this forum.
I am drooling over the Titan, but am with T-mobile US and can't switch anytime soon.
If I buy a Titan 3rd party, can I use it for voice and data on T-mobile? Will I get full speed data?
Thanks.
You will get voice and data, but only 2G speeds. That goes for both the international version and att version.
Any info on some kind of quad band version that will work on both AT&T and T-Mobile?

Titan is quad band according the htc.com
HSPA+/WCDMA 850/1900/2100MHz and Quad-band GSM/GPRS/Edge 850/900/1800/1900MHz
Shouldn't this work then? ATT's specs also say 850/1900/2100 MHz for HSPA/UMTS. T-mobile's HSPA/UMTS is on 1700/2100 MHz (according to Wikipedia). For the 2100 band, it should work, right? I am unsure as I am a simpleton and just comparing numbers and assuming that is all that has to match.
I would guess this would require an unlock.
T-Mobile uses both 1700 and 2100 bands for their 3G/HSPA+.
This is why it will not work.
I know because it pains me to not be able to get this device on T-Mobile.

Go with AT&T GoPhone if you have Titan (Simfree), i am enjoying Unlimited All, (Call + Text + Web 4G ) with only $50 a month . Titan can get HSDPA+ (i think) on AT&T.
Im using the titan, unlocked on t-mobile and it does run on edge. honestly its not tooo terrible but edge sucks. and i cant get picture messages. idk i just might keep my hd7, sell this phone and wait for something better on t-mobile that i can actually use hahah but i love the giant screeen
Does this mean the Titan would get 3G or better on T-Mo US now?
http://www.phonearena.com/news/T-Mobiles-consolation-package-3-billion-7-year-3G-roaming-deal-128-AWS-markets_id24956
AT&T and T-Mobile UMTS Roaming Agreement
AT&T and T-Mobile agreed to roam on each other's UMTS bands for the next 7 years following the formal withdraw of AT&T's merger offer. As to when that becomes effective I do not know; I've yet to get an answer from either AT&T or T-Mobile on the subject and that's assuming they'll tell you; it takes an act of God to get through to AT&T's equivalent of T-Mobile's Tier 1,2 and 3 tech support. We have both AT&T and T-Mobile; and in the here and now, neither are compatible on each other's high speed bands; I have the Titan with AT&T and the Rhodium with T-Mobile; my Rhodium unlocked for use on AT&T and despite 3G in Columbus, GA and Auburn-Opelika, AL; I can only use Edge on AT&T. On my Titan it's either "E" or "4G", no 3G. What I have noticed is the Titan favors 4G and seeks those towers which is great if you're in the city, but rural; forget it. It's all Edge out here. It will hit the T-Mobile tower which is 4 bars in our Opelika location but immediately go to either no service or a 1 bar sometimes on 4G and others on Edge. We all know that "4G" isn't 4G and of course "Unlimited" isn't unlimited and politicians and marketing gurus think we're all stupid.
Ok guys I have an atrix 4g running on t-mobile. My question is why cant I get 4g/3g on this phone ? T-mobile runs on the 2100 band and the phone does support that band so why no 4g or 3g? common sense would tell me that if t-mo runs 4g on 2100 and the phone is capable of running on 2100 that it would work. have searched for a total of about 4 hours or so over the past couple days and cant find a straight answer only thing i can find is that att doesnt run on 2100 band yet the phone does. thanks in advance to anybody that can answer and taking the time to read.
are you getting H+ or H? (This is "3.5g") The Atrix 4g is not a true 4g phone.
Because the 2100 spectrum that you're using the phone on now is part of the quad-band gsm which is edge/2g. The difference lies in the bands used for 3g/4g, in which case AT&T only uses 850/1900 and tmobile only uses 1700/2100.
There is also a bunch of things that include HSPA, AWS, WCDMA, and so on and so on but I don't know enough about that to comment.
EDIT: Also, the only phones I know that can be used on both AT&T and Tmobile 3g/4g are "penta-band" phones like some European Nokia phones and the unlocked Galaxy Nexus that needs to be imported as well.

Wcdma=utms=3g
Yes, WCDMA and AWS(1700), as far as I know, are both from UMTS and the differences in regards to 3G between AT&T and Tmobile lie in the spectrum use (850&1900 vs 1700&2100). And both AT&T and Tmobile use HSPA(+) based off their respected UMTS frequencies.
I just don't understand the "leap" in GSM technology that breaks the quad-band compatibility, that's all.

Also I've read 850 is att's main spectrum for large areas and 900 for T-Mobile. All higher spectrums are for smaller, rural areas.
If your looking for 3g maybe find a town or, buy a dual band amplifier? That's IF they have 2100 MHz band working where you are located.
Lower bands ie 850/900 are the download streams. 1700/1900/2100 are upload streams. If I'm not mistaken
Also a T-Mobile vibrant supports att, it also has our main band, 850mhz. Again which is the main large areas, like T-Mobile 900mhz. 1700-2100mhz for att/T-Mobile range is only as good as the towns that still has that band currently operating for hspa/3g data. I've seen alot of T-Mobile phones that have 850/1900/2100, and work on att. If they were 1600/1900/2100 did not for me.
You need that lower frequencies to ensure it to work. Then....
Also for regional based frequencies...
http://en.m.wikipedia.org/wiki/Universal_Mobile_Telecommunications_System
That link will let you know what that all really means.
I think you are mixing up gsm and umts.
GSM = 2G/Edge
UMTS (HSPA, HSPA+, HSDPA/HSUPA, WCDMA, AWS) = 3G
Have a look here. You will see they label "3G" as "UMTS" which is HSPA/WCDMA. A little more down you can see they label their data as "HSDPA", which is download, and "HSUPA" which is upload. Further delineating the speeds they label either one as UMTS for down and Edge as up, which to me tells me they use gsm for the upload and only use UMTS for download. Either way, there is not a T-mobile phone available that can be unlocked and used on AT&T's 3G, just 2G and vice versa. As I have previously mentioned, you will need a penta-band phone for that.

I am just merely stating that I have a motorola defy on ATT, and it worked great for a long time with great speeds before I got a motorola atrix and infuse.
Im not saying that every tmobile phone will have working talk/text, or data for that matter. I have just posted an idea, or atleast what to look for when you are cruising for phones not labeled for your carrier.
I was getting my motorola defy with the att "grand fathered internet" for 10 dollars a month and it was about 160-420KB/s down, and 80-190KB/s up. but some phones are capable of this, others arent. I have a general idea, and have played with several different carrier cellphones and used them with att and att's 3g data.
Rogers HTC Dream (x2 of them)
Telus Milestone
Tmobile Defy
Rogers Atrix
ATT Atrix (x2 of them)
ATT Infuse
Rogers and Telus actually use the same 3G bands as AT&T so as long as those are unlocked they will work. And I'm not saying an unlocked T-mobile can't work on AT&T, because they can (they both use quad-band gsm) but you can not use an unlocked T-mobile phone an AT&T 3G. That's all I'm saying.
Now, they did make an European version of the Defy that uses the 850 3G band but not the T-mobile "branded" one.
I'm going to stick to my guns on this one because I don't want to give anyone the wrong idea about interchanging AT&T and T-mobile phones and expecting 3G service. I'm fairly certain about this and unless someone can prove otherwise that's how I will think.

Upon further research, I have found this article, where under certain circumstances, you can use an unlocked AT&T iPhone with T-mobile 3G:
http://www.gsmarena.com/tmobile_usa_running_1900mhz_3g_in_some_areas_iphones_invited-news-3537.php
Now, this shows that an AT&T phone can maybe use T-mobile 3G but not the other way around. Again, I'm always up for learning something new but I need references/proof.
Well I do get att 3g on the defy and vibrant. I am currently getting about 300ish KB/s on them and 600+KB/s on my attic, I'm just going with the facts. Those facts are that certain T-Mobile phones will work with Att, provided they have 850mhz band. That allows you in most towns (near me) to get 3g
False.
300KB/s is Edge speed, which is only 2G.
http://en.wikipedia.org/wiki/2G
http://www.phonescoop.com/glossary/term.php?gid=107
That's why you get faster speeds on the Atrix because it actually uses 3G.
Again, both AT&T and T-mobile use quad-band GSM. Which is why you can unlock a T-mobile phone and use it on AT&T, and vice versa, but it is only 2G/Edge and NOT 3G.
http://www.phonescoop.com/glossary/term.php?gid=139
http://www.phonescoop.com/glossary/term.php?gid=3
Furthermore, here are the wiki pages for AT&T and T-mobile which both inlcude frequency charts outlining the technology (2G or 3G) each one uses:
http://en.wikipedia.org/wiki/AT&T_Wireless
http://en.wikipedia.org/wiki/T-Mobile_USA
Here are the charts:
AT&T:
Frequency Protocol Class
Frequencies used on the AT&T Network
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/HSPA 3G
1900 MHz UMTS/HSPA 3G
700 MHz LTE 4G
T-mobile:
Frequency Band Protocol
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
1700 MHz UMTS (W-CDMA)/HSPA/HSPA+ 4G (formerly 3G[34])
1900 MHz UMTS (W-CDMA)/HSPA/HSPA+ 4G
I check for facts and references, I'm only saying what I find in research.
Again, when unlocked, a T-mobile phone can use AT&T 2G/Edge, not 3G

hello all,
I was wondering whether it is possible to unlock the LTE radio on the Eu retail version. I think the chipset is the same and hence it does have the capability.
Thanks in advance,
Santanu Dey
Are you saying that your razr never gets 4G / HSDPA signal?
Don't you ever get the little 'H' on your connection indicator?

Not even LTE is 4G. It is called such for pure marketing speculation since LTE is still part of UMTS... it is its 8th revision, actually.
Cheesy, you should first ask your provider if they reach ~325Mbps. Vodafone, the european carrier with the best network, sells 48Mbps (HSPA++) as LTE, which isn't really.
LTE isn't yet fully ratified, actually.
Anyway, it works
For general information:
LTE is Long Term Evolution.
HSPA or High speed packet access and its derivatives are not LTE...
The modulation scheme is different as well as the coding and spectrum and Bandwidth. LTE works in 2 variations TDD and FDD, whereas HSPA/UMTS is purely FDD. Secondly, LTE works in 1.4Mhz, 5 MHz, 10Mhz , 20Mhz Bandwidth whereas HSPA/UMTS is only 5 Mhz.
Basically HSPA is a evolution of data access on UMTS network, as EDGE was in GSM network.
So , returning back to the same question..... Can we unlock LTE radio on the Razr? My operator Telia is already having commercial LTE network (300/100 Mbps DL)..
Beg my pardon I was not aware ( haven't done quite as much research as you guys it would seem ;D )
Can I just ask briefly, is LTE a cdma standard as opposed to gsm or is it something viable on both platforms?
LTE is basically a convergent network between the CDMA and the GSM domains. The radio standard has been designed in such a way that it shares the backward compatibility towards CDMA and GSM domains..."BUT".. LTE is much more bent toward the GSM/WCDMA domain than CDMA/EVDO domains,since it shares the same spectral characteristics of the UMTS networks.
WIMAX on the other hand is more bent towards CDMA/EVDO domains...
I have a INTERNATIONAL Samsung Galaxy S2. I am going to be travelling to the states soon. I am planing on getting the ATT Go Phone 50 dollars unlimited plan. My other option is tmobile. However i know they use AWS for their 3G connection but my friend is saying that their HSPA+ 4G network uses the 2100Mhz band. My question is could i use this network with my phone?
Thanks

Nope. Not how AWS works. AWS requires both 1700 and 2100, as it uses one for uplink and one for downlink. So if you go w/T-Mobile USA, you will be limited to Edge data speeds when not in range of wi-fi.
The other option you have is using one of the smaller networks that piggy-backs on AT&T's network, like h2o.
I don't know much about them though.
