I had an appt. today at apple store to replace my iPhone, so I fully backed up last night 5/20/10, and this morning, 5/21/10, I plugged my iphone in right before the appt. to restore and it started backing up again so I stopped it, and apparently it went over the full backup I had last night, is there any way to restore the backup from the 5/20/10, so I can have all my data back, without having to jailbreak?
