Ars Technica has gotten confirmation from AT&T that existing AT&T customers can purchase a new 3G iphone when it is released in about six weeks. A customer's existing contract will be replaced with the new contract. This is good news, since many current iPhone owners (myself included) want a new 3G iPhone, and I personally do not wish to be locked down to AT&T for another two years on top of my existing two-year contract. Call it early renewal, or whatever you want, but I'm happy with the deal.
