I have an iPad (not wifi) that I purchased the first day it was available at the Apple Store.
I had issues with it restarting after syncing, and exchanged it the next day. A couple weeks later, I did it again, as the problem still happened after each sync.
It continued to happen, and any Genius Bar visit or phone help I have received indicated that it is an iPad issue. It seemed to be getting progressively worse, restarting every few minutes after syncing for as long as I would let it.
I had tried everything, and finally found the issue(s). I removed all my photos (after trying music, apps, etc.), and it does not restart after syncing now. However, loading my pictures back in one by one is not possible – I have close to 4000. SO, I added all my albums with no problem, then tried events. I had to do them a few at a time, and ran across 5 pictures taken at different times under different circumstances in different events (some scanned, some downloaded from friends, etc.).
My question, finally, is there are probably at least a couple hundred more events. Do you have ANY POSSIBLE idea what the issue with the pictures may be? They load to the iPhone 4 (and to my past 3GS) with no problem.
Sorry for being so longwinded.
