I will be unlocking my I717 tonight, flashing blaze radio, and flashing JamieD's CM10.1 rom
Do the USSD codes word with AOSP Roms or do I need to run TouchWiz based roms? Especially *#2263# to force the phone into AWS HSPA+ mode?

*#*#4636#*#* on aosp. Some codes are different on different android versions. Optionally setting/ wireless and network more/ mobile network/preferred network type.
OK great.
Ill be using the I717 on T-mobile and i want to make sure i can take full advantage of the AWS HSPA (1700mhz) or the 1900 mhz HSPA+ (I am in a refarmed market).
Though I hear that AWS HSPA is +42 and 1900mhz is only +21

Using it on T-Mobile here as well. Seen as high as 16mbps download using the i717 blaze, i717 uvlg3, and also the official att uclf6 which would be on the 1900 band.
So try a few out and see which works best. Not sure but thought all bands were created equal, as per throughput. Maybe someone else can chime in.
Do i need to set it to WCDMA ONLY or Preferred?

Preferred will cycle between available edge and HSDPA frequencies.
Where wcdma only will provide HSDPA and no 2g.
So for me...preferred as any data is good data

Actually, the rumor going around the internet that you can only use At&t 1900mhz on the Vibrant is false.
The vibrant can also utilize wcdma 850mhz. So you should have no problems picking up both 3G signals from At&t.
I will work on making a how to video that shows how to make the vibrant pick up the wcdma 850, takes litterly 2 minutes to do.
Remember, you might run into other annoying problems such as setting up visual voicemail to work with At&t.

I saw Band V in the service menu, but I had no luck enabling it, so it seems; here in NYC ATT is using UMTS Band II and the Vibrant has no issues picking it up, I am getting upward to 3Mb/s down speeds

Umm interesting thread, similar to what we are doing.
So are you saying you are not able to pick up the wcdma 850 (FDD V) band? We set this up on a friends phone, with his At&t sim, it works.
Can you try setting your phone to wcdma 850 only, and drive to a location that has 850 signal, then check under basic information, you should be getting at&t 850 3g.

Dear Vietphunguyen, there seems to be controversy. We know for certain the vibrant can pick up att 3g signal using 1900 band, but the question is, what about 850. Me and a friend believe the vibrant can also get 850, but that link the other poster provided is something to note also.
Be safe, don't purchase the vibrant yet, until we test this more. 2 make sure you can pick up both 1900 and 850 bands.
I dont know much about the Vibrant just yet, but if its anything like the iPhone on TMO's towers, it might not work. The problem was with ATT using a single band for 3g (1900mhz) to send the recieve but TMO uses 2 bands, 1 to send and 1 to recieve... If this helps at all I dunno! lol

Thank you, just to clarify, for people visiting this thread.
At&t uses 2 differend 3G bands, one is 1900mhz and the other is 850 mhz. At&t is starting to implement 850 towers. Naturally, you would want a phone that picks up both bands.
Now, we know for CERTAIN, the VIbrant will 100 percent pick up At&t 3G 1900mhz signals. The question is, which we are uncertain of, will the Vibrant also pick up 850mhz band 3G signal, incase you hapen to drive to an at&t area that only has this band.
clearer?
I recently purchased an unlock galaxy s2 i9100. It is supposed to be GSM unlock with HSPA+ 21Mbps/HSUPA 5.76Mbps, EDGE/GPRS Class 12, Quad band GSM 850/900/1800/1900, Quad band UMTS 850/900/1900/2100 hardware capabilities. since I have gotten the phone i have not been able to connect to anything but edge. Tmobile assured me i had the correct APN setting. I would like to know if anyone know what I could to to enable the HSPA+ T mobile US uses UMTS 2100 to connect. I rooted and flashed the lite'ning rom.

Nope you won't get hspa speeds on Tmobile with the current international version. You have to wait for the Tmobile variant. International version gets
3g speeds only on att.

This is correct. However, it's only used for one way traffic (either uploading or downloading, i'm not sure which). UMTS 1700 is used for the other direction of traffic on T-Mobile. This means no 3G/4G without both frequencies.
Your 2 options:
1. Get a T-Mobile phone.
2. Switch to AT&T.

thanks for the quick and concise responses. I have a clarification: does this mean that I when Tmobile comes out with the variant my phone will be able to upgrade to Hspa via a rom or radio update or that if i want to keep this model i will have to wait to swap it out for the tmobile version

The I9100 will NEVER work on T-Mobile. The SGS2 that they are releasing has different HARDWARE. There will never be a way to make the phone you have now work on T-Mobile 3G.
As others have said you'll need a different phone in order to get it to work on T-Mobile USA's 3G/4G frequencies.
You'd need a penta-band phone in order for it to work on all of them. I think Intel is curently working on that or already did but that's all there is. You'd need both 1700/2100mhz in order to use it with 3G.
I don't get how people don't research before they buy!!

Hello All,
I am on tmobile and had samsung galaxy s before i got SGS2 from at&t (my wife upgraded). i unlocked/rooted the phone after reading through the posts and it worked like a charm!
My concern right now is that I am always on edge data network with tmobile. can anyone help me on this. Tethering is also not much of use when i am on the slowest connection. Please help.
Can't do much about it since AT&T version doesn't support the 3g/4g band for T-mobile.
At&t gs2 doesn't support t-mobile frequency for 3 g.

No only AT&T.
My guess is that international version supports all the bands not the carrier branded sgII
^Even international version doesn't support T-Mobile 3g/4g (HSPA+) network.. Not many phones support their network. Or maybe it will.. but not everywhere
AT&T SGSII
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
T-Mobile SGSII

3G Network HSDPA 1700 / 2100
International SGSII
2G Network GSM 850 / 900 / 1800 / 1900

The AWS (1700) bands are supported only by a handful of carriers. It doesn't exist at all in Europe and Asia. There's little reason for manufacturers to include it on their global phones as so few people use it. It's the reason the T-Mobile SGS2 has a Qualcomm chip instead of Exynos like the rest of them. After the merger, it won't even exist in the U.S. any longer as AT&T plans on using it (1700) for LTE. If you want versatility and the ability to use unlocked phones, change to AT&T.

In order to get T-mo 3G, a phone must support HSPA on 1700MHz AWS band, not 850MHz. As such, only phones from T-Mo or some Candadian carrier support 1700 band. Rest of the world use 900/2100 for 3G and AT&T uses 850/1900 for 3G/4G.
You are never going to get 3G on T-Mo on any phones from AT&T. Period. Give it up.

TMobile uses 1700 up, 2100 down. If the handset doesn't support 1700, you are out of luck.
Correct. Many phones support the 2100 MHz International band.
T-Mobile's network is weird though, and uses both 1700 and 2100 MHz at the same time.
My guess is that UMTS1700 support and not 42 Mbps HSPA+ is why the T-Mobile variant of the GS2 is such an oddball phone.
NO AT&T phone and only a small handful of international phones support T-Mobile's 1700 MHz band.
Similarly, only one or two T-Mobile phones (The Vibrant being one of them) support any of AT&T's 3G bands, but none support all of AT&T's 3G bands to my knowledge.
The interesting thing about this entire thing is that if you go into the modem band selection it lists 5 different wcdma bands including the aws 1700. I enabled those bands and tried using a tmo sim but alas it still only worked on edge. It may have just been there cosmetically rather then actually supporting aws bands. use dialer code *#2263# to access the band selection menu. Maybe there is a way to get it to work.

Typically, the s/w supports multiple versions of h/w. Just because an option's in the menu doesn't mean the h/w's available to support it. The same thing happened with the T-Mobile G2X. It was supposed to be quad-band, the option was in the ROM, but the radio wasn't there to support all the bands.
I'm trying to do my research, and the phone seems to support the right frequencies.
http://shopamerica.htc.com/cell-phones/productdetail.htm?prId=41599
https://www.t-mobile.com/shop/Phones/cell-phone-detail.aspx?cell-phone=HTC-One-Glacial-Silver
But then I saw this article (http://www.pcmag.com/article2/0,2817,2416536,00.asp) saying that the DE won't really support T-Mobile LTE. Is that true?
I'm also concerned that I won't get Wifi calling with the DE on T-mobile.
Please help me figure this out.
Edit: looks like wifi calling is possible (not out of the box) while HSPA+ and LTE won't work that well.
I think it dosent support's 1700 band which t-mobile uses in some places.
I wont get it
why take a risk?
The Developer Edition supports these frequencies:
HSPA/WCDMA: 850/1900/2100 MHz
GSM/GPRS/EDGE: 850/900/1800/1900 MHz
LTE: 700/850/AWS/1900 MHz (US)
That means it only suppers 3G (HSPA) on 1900 Mhz, but not on AWS (1700/2100 Mhz). So you will only get 3G if you are in a "refarmed" area, where T-Mobile has refarmed some of its 1900 Mhz spectrum away from 2G to 3G. People's experiences vary.
I don't see any reason why the Dev Edition won't work with T-Mobile LTE, since it supports AWS for LTE, which is the frequency set that T-Mobile and AT&T both use. I'm not sure why PC magazine feels unsure about this. If you search around, I'm pretty sure there are already people in this forum reporting getting T-Mobile LTE on both the AT&T version and the Developer Edition (which are basically the same phone). There also appear to already be other threads on this topic, so you can find more people's experiences if you search around.
As for the WiFi Calling, you will definitely not have access to that. Someone may be able to port it at a future time, but I wouldn't count on it.
You will be able to flash a T-Mobile Rom on the developer edition.

Tmobile with fine with my dev edition in NYC with stock rom and radio. But the speed seems to be slower than what people have been posting here, 6~10mb download and 1~2mb upload. I am not sure if it's a regional issue.

Just got on T-Mobile's LTE in Houston. I'm running stock AT&T Rom & Radio. I can get LTE in different spots. When I'm at work, I can only get Edge. I then flash to a modified modem GT-N7005amss thingy that's floating around here and I get HSPA + (21.6 Mb/S) when i'm at work, but when I leave it never picks up LTE again. Is there a modem that I'm just not seeing that will enable to me to get both so that I don't have to keep switching modems? Can one be created?

unfortunately no. The ATT modems are the only ones that will pick up LTE on tmobile.
The tmobile radios are from other devices which do not support lte. They also operate on the 1700mhz band where the att modems will get 4g under the 1900mhz refarmed band with tmobile.
I know I use tmobile on the latest att ucmd3 jb modem and pull about 8-10mbps down. The key for me choosing was the incredible upload speed which was 2-3mbps.
You can flash the radios back and forth before and after. Takes 2 min. Only other option.

not that I found. If your on a touchwiz based rom then the *#2263# into dialer cannot select 1700mhz band under wcdma option using an att modem. On the t mobile modems you can.
If your on a cyanogenmod rom or other then *#*#4636#*#* can only select from gsm/wcdma or preferred. Or under settings/mobile network/preference. The lte option will only show for att modems.

The modem.bin or mdm.bin that you flash is a binary file and cannot be edited unless you are at samsung.
it might not work but then again it might...
try a Canadian rom and modem...
it has a easier menu to switch from wcdma- lte -gsm
(settings-more settings-mobile networks-network mode)
and many providers here do there best to make sure snow birds have access to all the US networks
so they can financially rape you.
or i could be wrong and it will be worse...
