I wonder what makes you think that an iPhone user cannot sell their used phone (via ebay or other similar venue), buy any newer model (3G if available) and get that activated under their current AT&T contract? We know they can’t get the iPhone activated by *another* carrier, but, within their own contract, they may well be allowed to either swap the SIM card or activate a new iPhone. I think, unless there’s some direct info from either AT&T or Apple about that, we shouldn’t assume anything.
The price of an iPhone is xxx WITH A TWO YEAR CONTRACT WITH ATT. So, selling one iPhone doesn’t remove you from the original contract (unless you’re fine paying the cancellation fee), while your new iPhone purchase will require a SECOND two year contract.
