Hey, My iPhone 2G works fine except when someone calls it won't ring.. I don't get the call unless I actually unlock the phone and then I see "one missed cal"l or "text from so and so". Any ideas if this is a software issue? I'm running 3.0 JBed/Unlocked. I upgraded to 3.1 and back down to 3.0 in order to unlock if it makes a difference... Really frustrated.. thanks so much.
