WHAT I DID: 1) Backup iphone to itunes 2) upgrade iphone to ios7 3) tried to sync, said it needed itunes 11.1 - upgraded itunes to 11.1 4) phone (ios7) and itunes (11.1) would not sync. 5) reverted back to latest ios and latest itunes 6) phone does not sync - gets message "itunes was unable to load data class information from sync services." I have my latest backup from /library/application support/mobilesync - all of the information and data is there - it is just not being recognized as a restore option. Any thoughts? I'm kind of stuck on this one. I would really love to put all of that back onto the phone, in stead of paying for a service to download and extract all the pictures / data. Thanks in advance. Ps I also realize that I should have backed up to icloud instead of itunes - but its too late!
