    i have an iPhone 3gs with a serial number **938*****. I'm fairly new to the whole unlocking process and was wondering how to unlock my phone for T-mobile use? i know its after the 35th week so I'm completely lost as to how to go about this!

    The firmware is 05.16.05 and the baseband is 5.1.1

    Actually, the firmware is 5.1.1 and the modem firmware (baseband) is 5.16.xx

    You can install the iPad baseband to unlock, but read all the warnings and consequences carefully as it cannot be undone.

    Your reference to 35th week is for the year 2011 (xx135xx) but actually any phone made after the 27th week of 2011 may have the newer bb chip which cannot be flashed with the iPad baseband.
