Wife has changed her mind on the phone she wants. How long after I cancel the order will I be able to preorder. The phone is already on the 3-4 week period and so would the changed phone so that's no big deal. Alternatively, if it is not restored instantly can I use a third line I have and then just activate it for her number when it arrives? And then upgrade the third line to Next the following year when I want to upgrade it?
