Hi, I got my iPhone today and unlocked it with Ziphone. Since then my iPhone has been very unstable - apps keep crashing and the iPhone reboots every five minutes or so. I unlocked 1.1.3. Updated to 1.1.4, unlocked again. And the problem's still there. I must have tried restoring a hundred times only to see the same problem after unlocking. Any ideas what I should do? thanks, M.
