I moved to AT&T and got my 3G in January. My question is if I want to upgrade to the new model when it comes out this summer, will I be able to do that and still get the discounted pricing. I know a lot of this is speculation, since, at least officially, there is no new iPhone yet. But I they usually offer a discounted rate for new customers. But if I want to upgrade and am willing to sign a new 2 year contract would I get that discount. I just don't want to have to be out like $400 for a new one. Any ideas on how this is going to work?
