So all of the sudden, when I plug my iPhone 4 into my PC, iTunes prompts me to either set it up as a new iPhone or restore from a backup (which I haven't done for a week or so). What the heck? The phone isn't in any kind of DFU mode or anything (it's working perfectly normal and without issues). I don't want to have to restore it to some old backup and lose stuff from the phone. There's no option for me to back it up or sync it. Anyone else ever have an issue like this?
