Unlock? So in advance let me apologize if these questions has been asked and answered many times before. I have a jailbroken iPhone 3GS 32 gig that I would like to unlock Is this possible? Here are the specifics. Version 4.3.3 (8J2) Carrier AT&T Modem Firmware 05.16.02 Serial Number 5K03866 (first 7 digits) If this is possible, once unlocked, I would like to give this to my son to use as his AT&T phone (with no data plan or usage). How do I make sure the data portion of the phone is turned off so as not to be charged for a data plan by AT&T? Please answer as if you are talking to a second grader. Although I am fairly computer literate iphones baffle the crap out of me. Thank you in advance for your help.
