I've read in a couple threads that it is disadvantageous to the iPhone 3GS battery life to restore from a backup. I understand this. What I DON'T understand is how you guys can reconcile doing that and, at the same time, losing all your past SMS messages, your past notes, past alarm clock settings, Maps bookmarks, Weather locations, and ad infinitum app data.....You literally just start afresh and get rid of all those in the process?
