If I setup the iPhone as new, is there no way of backing up my SMSs, contacts, game settings and such?
I have the same problem, by the way. Tried every trick in the book and my battery has today drained 20% in less than 10 hours doing nothing but checking the clock now and then. Absolutely scandalous, and not a word from Apple to help us with it. I'm starting to regret buying this phone when I can't even revert to a previous version of the OS.
Edit: One strange thing I noticed was that my "Call Time" during today was nearly identical to my "Usage" time. Why is it logging that I've called for 8:45 hours out of the 9 hours I've had the phone turned on, when I haven't made a single call?
