3GS 3.1.2: Blackra1n Jailbroken, unlocked, stuck on emergency screen

[vipari]

I have iphone 3GS 32gb with the late MC133LL model with 3.1.2 (7D11) out of the box. modem firmware is 05.11.07. Bootloader version 06.04 I bought this phone in decemebr refurb from ATT.

Currently i am with ATT for a month and was planning to cancel the contract with them. Before cancelling i jailbroke the iphone with Blackra1n with att sim inside. Then installed cydia and blacksn0w. The jailbreak worked fine i guess, since i see blackrain cydia etc on the home screen. updated cydia at first start and am not sure/remember about the prompts that came up and if i said yes or now. The cydia screen says "This device has a pending TSS request"

Now, the interesting part,
When i switched the sim to Tmobile, i see the emergency screen. and this message " Different sim detected. Connect to Itunes"

At some point i was even getting the tmobile carrier and edge sign. I could even recieve calls, but i cannot get out the emergency screen. Once i remove the tmobile sim, i see the unlock screen and get into the phone.obviously everything works, but with no sim i cannot make calls.

So basically with the tmobile screen, i cannot get out the emergency screen mode even though its jailbroken and unlocked. ( since i can recive calls on the tmobile number in the iphone.)

Since i could get anywhere with this, i figured i would replace the phone with att since i am still in contract. And therefore tried to restore the iphone. Here is the message i get:
"This device isnt eligible for the requested build"...so bsically i am stuck. I cant restore the iphone, do not want to update 3.1.3 since there is no unlock etc and cant use the iphone with Tmobile presently.

Any ideas, how to get out of this situation. Ideally i want to unlock, jailbreak this iphone to work with Tmobile.

Do not update to 3.1.3 - whatever you do.

Do you know what bootrom you have? If your phone was built after week 40 or so, you will only be able to do a tethered jailbreak, which means you will have to plug in your phone and re-jailbreak every time you reboot. You have to go into DFU mode to see what your i-boot version is (if it's 359.3.2 you're out of luck).

If not, try re-jailbreaking with Blackra!n (once again, do NOT update to 3.1.3). Re-install Blacksn0w. Try this tutorial: (skip to step 5 since you already have 3.1.2 installed)

After you restore, jailbreak, and unlock, follow the instructions in the carrier bundle thread.
