Brief scenario leading up to my question: I've had my iPhone 4 since release, and I've been happy with it. I recently moved, and I started having trouble with dropped calls in my new home... and I thought this very odd, since neither my mother in law's iPhone 4 or my wife's iPhone 4 have any troubles at all in this house (and she talks on the phone a lot more than I do). Even more odd is that even though I bounce between one and three "bars" here in my new house, 3G is usable and even stable enough to use Pandora. I decided a trip to the Apple store wouldn't hurt. The tech plugged my phone into his diagnostic software and told me that there were no dropped calls recorded from the perspective of the phone, so he pointed the blame at AT&T. However, he also noticed some charge cycle statistics that he felt were "impossible", and suggested that something was messed up in the phone's "settings" (a rather ambiguous term to be sure). He sent me home and advised that I do a restore on the phone and try it out. I followed his advice. Since I haven't talked on the phone a whole lot since I got over the new home calling spree, I've had little opportunity to test it. However, one major frustration has resulted: all my app data and save games are gone now. (Backed up of course, but gone nonetheless.) So here's the question: I want my app data back. Badly. However, I'm concerned that if I restore from a backup, that the alleged bad "settings" will come back. Is this doable in any way? Furthermore I'm not really sure what "settings" he was talking about. Prior to taking it to the apple store, I did some things on my own like resetting the network settings, but I was still dropping calls. Can someone fill me in on what my options are? Resolve some of the ambiguity over these evil "settings" that were bad? Whether they will return with the "settings" that get restored when I restore from a backup? Thanks!
