No-Contract And No-Activation iPhone 3G Coming To AT&T?

Nothing is concrete yet, but starting March the 26th, AT&T is going to offer current iPhone 3G models at no-commitment bases. That's right, no general contracts to obligate and no activate to follow, but you must have an existing AT&T line to qualify for the offering.

It's a great deal if you are in the market for an iPhone but afraid of the two years commitment. The term also restricts sale to just one device per line, meaning only one per customer. So there, what's AT&T up to with the new offering? Just another general sale or flush out stock, anticipating a new product?
