Hi, I just got my first Apple product a few weeks ago, an iPAD2. Now I want to upgrade to IOS5, but I cannot for the life of me get my iPAD backed up. I have tried rebooting both it and the computer, changing settings, etc., and it still just runs for hours every time I try to back it up. There's not that much on it, but I don't want to lose the emails, calendar, etc. that are there. Would be most grateful for any help.
