Long story short, I have an iPhone which is freezing constantly. I just got the phone replaced, and as soon as I restored from an old back up, the problem came back. I have a feeling I will need to set up as a "new iphone" and start from scratch. This is aggravating because I don't want to lose my text/imessages, and I dont want to lose application data. What will I be losing exactly and is there any way around any of it?
