A:AnswerI’ve found ordering it through BB super easy. At checkout you’ll have the opportunity to pay outright or renew the existing contract. You’ll also be able to trade in a previous phone if you want (you’ll have to take the phone to ATT) and have the opportunity to add ATT next which allows you to trade in phones quicker.
The only thing due if you chose to renew your contract is you’ll have to pay taxes on the phone at checkout.
Honestly it’s a pretty straightforward process.
A:AnswerYou can deactivate you old phone at anytime, and activate your new iPhone anytime, we kept the old iPhone active for about a week before activating the new iPhone
