I was forced recently to trade in my iPhone 4 for a 4S
Do I need to register this new phone all over again, or is there a way to just transfer all of the current information to the new phone? Like if I plug in the new phone to download everything/sync everything is there a way to get it to recognize the device the same way it did the old one? What problems will I encounter? I have to mail the old phone back in 5 days, and I want to make sure I do this properly without a headache.
