I have a 1.12 OTB iphone. I have been using a turbo sim card. It was working fine until the bottom DOCK all froze up. Therefore, I cannot make calls, check email, safari or IPOD. Everything else works but cannot make or answer calls. The phone does ring and allow voicemail but cannot check it because the Bottom Dock is locked for some reason. Everything else works on the phone. I needed help to fix this problem and help with unlocking this phone so that I don't need to use Turbo sim and Iworld.

Any help is greatly appreciated
