sync session failed to start
When attempting to sync my iPhone 4S it stays stuck on step 1/5 "starting sync session" and after 5 minutes times out and gives me the error "iPhone could not sync because the sync session failed to start."
I'm running the latest version of 10.7 on my iMac and iOS 5.1
I sync most content with iCloud and iTunes match but need to sync a couple iPhoto albums and ringtones to the phone,
So far I have
-hard reset the phone
-DFU restored the phone (set up as new afterwards)
-Uninstalled and reinstalled iTunes
-deleted mobilesync files in library folder
-Replaced the iPhone at the genius bar
Still no luck, any suggestions????
Thanks!
iPhone 4S, iOS 5.1
