Sucks that you are all having problems?
Downloaded iTunes 11.1 from my dev portal backed up phone then option clicked restore to GM ios7
worked a treat as usual
will try again with another test handset
good luck
I'm not having a problem backing up and installing GM. Once completed I cannot restore my phone from my backup onthe computer. This is when I am getting the data loss sync services error. I also downloaded 11.1 from dev portal
