An agent store is a store not owned by ATT. There are stores around here that sell ATT, Verizon, and Sprint phones. These are agent stores. They are ran by a third party. Also a lot of mall kiosks are not ran by ATT. Those are also agent stores.
I don't like agent stores because the phones are usually more expensive in their, than they are in the corporate stores.
-Buts its understandable because when you OWN an agent store you gotta make a profit so its plausible that the phones would cost more
No. Only corporately-owned AT&T stores will have the iPhone 3G. That cuts out Wal*Mart, Best Buy, Radio Shack, and all the AT&T agency stores. The only non-AT&T stores that get residuals will be the Apple stores.
