My wife's 3GS is having battery issues since she didn't set it up as a "New phone" when she switched from her 2G iPhone. She restored from backup instead. There are reports that that can cause the 3GS to report the battery info incorrectly. The problem now is that she has some apps with quite a bit of data in them for work. Is there a place where that app info is stored in OS X? Is it possible for me to restore her 3GS, set it up as a "New phone" instead of "Restoring from backup", THEN individually copy the data for those apps back to where they're stored in OS X?
