Can I Unlock Without an AT&T Account??? - AT&T Samsung Galaxy S II SGH-I777

I'm thinking of buying a used one of these off craigslist ... but I'm on tmobile and I'm worried that I won't be able to unlock it without having an AT&T account first .... Can I unlock one of these without having an AT&T account? Most steps I've read talk about downloading an unlocker program from the market ... but without an AT&T sim card in the phone I don't think I'll be able to access the market ...
What do you all think?

You don't have to have cell network to connect to a wifi and log into market. You will need to root it also before those apps will work. Just fyi though. You will NOT get 3g/4g on T-Mobile

Thanks for responding!
3g/4g only involve data speeds, right? I have wifi at home and at work and do not use a data plan ... So I can root and then unlock on my home wifi without any AT&T account?

I see no reason you can't. I have done lots of phones that way.

Do you or anyone else know how to check if I have the dreaded KK6 2.3.6 version?

I'm using my unlocked Skyrocket on T-Mobile and I am getting 4G Speeds.

Absolutely nothing considering unlocking the 2 phones is a completely different process. On the i777 we can do it with root only. We don't have to call at&t

wait a minute. the SGS2 is being sold unlocked already from most places. so if you buy one it will just work on tmobile USA, just pop in your sim and go. however the SGS2 will not support tmobile USA 3G so you will only be stuck on EDGE/2G. nothing can change that.

nope. TMobile US has modified 3G as their 4G (HSPA+). I believe it is the same band as 3G (HSPA/UMTS)... but I could be wrong.

no that wont work either unless the phone is specifically made for tmobile usa 3g bands. when the USA versions come out, they are already confirmed for ATT, verizon, etc, but no tmobile. none of those versions will work on tmobile.
this has alreayd been covered, and the only choice you have is the samsung Hercules coming in place of the SGS2 to tmobile.

No it wont, the vibrant had one of att 3g bands so it could partially work on att. The galaxy s2 has NONE of T-Mobile bands, so it wont work period. It just wont work man no matter how many times you ask. Search the forum this has already been covered in depth.

[Q] SIM Unlock Samsung Galaxy S2

Not finding reliable infor on this anywhere. I need to do a SIM unlock on my S2. AT$T says "the manufacturer provides this code", and the manufacturer says that "AT$T provide this code". I say, I'll get what I need from XDA, the only reliable source of info. How do I SIM unlock this damn phone?
moderators will tell you to do more searching next time. This was easy to find.

I believe if you're with them (AT&T) for more than 6 months, you can ask them for the unlock code (say, for travelling aboard)

Well this phone is a bit different then most (like our Recovery being part of the actual kernel) so perhaps other phones don't have a simple software unlock and you HAVE to get the code from ATT. I know my old Moto Backflip didn't have a software option.

I'm reading a lot of data issues with ST. Are you using an ATT Note i717? Mine is rooted with a JB rom.
Soft cap is ~2GB for data on At&t compatible sim card. Not sure about T-Mobile compatible sim card, but I think I remember reading on HoFo that it was around 5 gigs.
I received a call from them when I hit 2.1, but I haven't hit that mark since.
If Tmo existed in IA, I would switch to the $30 prepaid since I hardly talk, and when I do, I generally use GV

So I was trying pre paid stuff like straight talk and Tmobile, you can use the sim cards as it is unlocked from factory but you must root it to edit the APN or the settings to get to data to work. In simple terms you can use it stock outta the box with just voice but u must edit apn settings to get data to work.....and its slow or crap compared to verizon and unlimited data..

I've been using mine on straight talk with their at&t sim card with the $45 month plan. Of course you have to tweak the apn but mine stays connected to hspa+ at all times and it's plenty fast for me. No complaints at all. I've read they have a 2gb data cap before they throttle you but I stay on wifi at home and work so I've yet to break the cap after using the service the past 2 months. For me, straight talk has been awesome.

ROOT / SU Question / Mega 6.3 / USA / AT&T

Anyone,
I'm not an android noob, but I left Android a few years back (2.3.3 / 2.3.4) due to work changing to iPhones for data encryption reasons. I came back to Android when more Samsung phones started supporting ODE (on device encryption). I would like to root my phone and have done so on other Android phone's using SuperOneClick, CWM, etc.
I am reading that there is a secure boot loader on the AT&T version of this phone in USA, so I am screwed in gaining root access to the device? I'd really like to delete all this bull**** bloatware they've installed... and a tethering app without using the carrier option.
Can anyone help?
I have the AT&T version as well. I'm not 100% sure that the bootloader is the reason for no root yet. Other phones have locked bootloaders and can still be rooted.
Running custom roms might be another story. I get the impression that because this is not a "mainstream" phone that it does not get top priority. For example, the Moto X on AT&T has a locked bootloader and that's rooted already, but it's a very popular phone.
Hopefully we'll get some love sooner rather than later. I would be happy with root along with an easy way to go back to stock.

No boot loader unlock, no root, so no custom ROMs as yet.
