Hello, Ive tried everything. But I cannot Jailbreak or unlock my iphone. Im running on windows 7, i phone version 2.1 (5f136), serial number:868451xdy7h, model:MB702LL, Modem Firmware 02.11.07 Ive tried every guide, But always get stuck. For some reason it does not allow me to upgrade the firmware to 3.0 in my itunes 9. I go to itunes, click Shift+restore And In the place where I downloaded the firmware it does not find anything but folders.. All help appreciated, If you need me to be more specific about something please ask. Thanks!
