    Hey!
    I've recieved my PhoneBook SIM (or it should be), the weird part is that the SIM is all white, no brand, no nothing. Is there a way to know if this SIM will work before hand? I mean to know if this is the SIM's that should help me bypass the Emergency Call Screen.

    Anyway, a couple of days ago I asked about a weird error I got. I have a 3GS 3.1.2 BB 5.11.07. It's unlocked with Blacksn0w. I tried to uninstall it and install the new untrlasn0w (1.1-1) however no matter how many times I tried it keeps searching and if I put on and off airplane mode I got "SIM Failure" popup and "Invlaid SIM" on the top left corner. I tried reseting network settings, hard reset (holding home + power) everything.

    I'm afraid cause I want to upgrade to 4.0/4.0.1 but if I can't manage to get the unlock to work I will kill myself!!!!!


    Thanks!!

    Awesome, but I read that this fix is when you upgrade to 4.0/4.0.1 and activate with the PhoneBook SIM. And the error is "Different SIM" but my error is "SIM Failure".

    However I just testing the ultran0w still in 3.1.2 and get that error, also I saw around the WWW other few people getting this error, specially iPhone4 users. I'm just very scared to fall into this troubles after upgrding and getting lost forever!

    Can you clearify if I'm wrong?

    Thanks a lot pal!

    If you have the oldbootrom, then at jailbroken 3.1.2 by Blackrain, you can restore to an hactivated custom firmware made by Pwnage tools of Snowbreeze of iOS 4.0.
