I got a 5 and gave my wife a 4. The Target rep was great and already put my wife's contacts, pics, etc. on this phone now. I was going to do a first-time backup for her now (it's been a couple weeks since we switched phones), but I'm getting "set up as new phone" or "restore from backup of" (my older phones). She is happy the way her phone is now. I don't want to delete anything. If I do "setup as new phone", will it delete anything on her phone? Thanks in advance.
