AT&T has just informed me that the information they provided this morning was incorrect and they apologize for that.
Here's what AT&T had to say:
"If you bought the phone on or after May 27, you have to exchange it. If you're buying a new iphone and you bought your old one before May 27, we don't require you to turn in the old one."
Now I feel confident, because my contact at AT&T knows what's up. I'm told "there was some confusion on this and it's been 100 percent clarified."
So again ... if you want to upgrade if you bought after May 27 you must turn it in for a free iPhone 3g but upgrading doesn't require turning in your old iPhone.
I checked and rechecked before posting and was just told by AT&T that the info was incorrect. I wanted to make sure the correct information was updated as soon as possible.
And, regarding the old iPhone, here's what I'm told: "Details are not available yet on deactivation - i.e. you keep your old
iPhone and you want to use it as an iPod."
I'm assured I'll get that information just as soon as it comes out, and I'll make sure I let you know as soon as I do.
Thanks for calling.
