If you get stuck in the restore loop
If after you installed the new firmware and you are stuck in a restore loop (meaning once it finishes and loads back up in iTunes) choose to set up a new phone once the sync starts cancel it. The phone will then show up as normal in iTunes . You will have to uninstall all your apps and resync any ringtones and songs onto your phone. Be sure to unconnect the phone after this first sync that removes all your apps. if there are any apps still on the phoen delete them fromt he phone by holding an icon until they jiggle tap the little x to delete. After all remaining apps are deleted do a hard reset. Be sure that the phone is not busy when you do the hard reset. That circle thing that shows up when you send an email will show up if the phone is busy. Once you reset turn it back on and connect to computer and begin reinstalling your apps. I do four or five at a time. Remember to do a hard reset between syncs. You phone should be working great and backingup pretty fast.
