Ok just a FYI dont update to 4.3.5 decided to on my pure iPad I got to sync and not iTunes crashes every-time !! Rebooted ipad etc no go even did a restore. No issue at all even right before the upgrade I'm running newest os iTunes on windows 7 after quick google this os caused by syncing videos in your photo section so if u uncheck "include videos " all is fine just glad I didn't do my iPhone just wanted to share save someone some trouble
