iphone 4 delivered tomorrow. Need some tips setting my dad up to use my old iphone 3g. A few questions: - I know I can easily just swipe in his sim card and what not and it works fine without a data plan. But if I want to restore it and go through the activation process for a new phone, will this alert AT&T that my dad isn't on any current data plan? - I remember this was an issue before, but is there really no way my dad can transfer over his Contacts and what not from his Samsung free phone onto the iphone?
