I plan to get the next iPhone 5S (or whatever it will be called) this fall. I have the iPhone 4S. I have a few questions: 1. Is it safe to restore from a backup or should I set it up as new? I'd prefer to restore it from a backup. 2. Does it matter if I restore it from an iTunes backup or an iCloud backup? I assume it would be much faster through iTunes. I'm going to be in college this fall, and I have no idea what the speed of the internet connection will be.
