I had my iPhone for almost six months without so much as a glitch. I installed 1.1.3 on Jan 16th and I started getting 5-6 Reboots a day. Playing a song and *Poof* reboot. After a couple of days of the reboots I reloaded 1.1.3 and it continued to happen. The following day I got a BSOD (Black Screen of Death) Apple Logo with Diagnostic information on the boot up screen. I took it into the apple store and they switched it out for a "New model", the Genius updated to 1.1.3 and about two hours later it locked up. Mid-swipe to login to the phone and the cursor stopped. Rebooted. I woke up the next morning and it was locked up again. It locked up again around lunch and then at 8pm. I took it to the apple store where another customer was having lockup issues as well. They replaced the phone again and I denied the Genius from updating to 1.1.3. I re-sync'd my info back to the phone and deleted my old restores (in case that was the cause of the failures) but I'm now gun-shy to upgrade to 1.1.3 again. Is anybody else having issues with 1.1.3? Oh non-jail broken, no third party apps were installed FYI.
