    I have an iPhone 3gs 5.0.1 model mc136ll and i need to unlock it for tmobile. Is that possible? I tried for a few hours last night but everything i came across said this phone was made after the 35th week of 2011 because of the model number. But that is impossible because my brother has had the phone for over two years. So i guess my first question is if it is possible and if it is, then how do i do it? Thanks guys.

    1. Look at the 3rd digit (year), 4th and 5th (week) of serial #s of the iphone and see when it was made. I will be more conservative and look at week 30th because that what I hear.

    2. Understand what the consequences of an Ipad baseband on an Iphone. That is how you will be able to unlock this phone. See the following link for this info directly from the dev team.


    3. Once you still really want to do it, then visit iclarified.com to get step by step tutorial on how to do it.
