I just got a unlocked and jailbroken iPhone 4. It has version 4.0 and modem firmware 01.59.00 for the life of me I cannot get data or mms to work. I dont have the option to edit network so cannot manually enter the Simple Mobile information. I need help as to what I need to install to get that button to appear so that I can edit the network info. Any help and walkthrough would be greatly appreciated.
