Said earlier you're not able to cancel order once you place the order online
. Local store may help you to cancel if you wanna get it faster and buy
again in the store. Their billing and order processing departments are
poorly disjointed. Don't even think about return. You may end up with
nothing but its so-called 'smart return' label which is famous for turtle
speed and nowhere to track.
Stay away from AT&T.
Btw,watch out your AT&T bill. They sent me the billing statement after I
returned the device and I didn't even activate the phone.
