If any of the thousands of people who waited in line two weeks ago at Apple and AT&T stores to purchase the iPhone have encountered buyer’s remorse, Friday is deadline for a full refund.

Both Apple and AT&T will accept iPhone returns within 14 days of purchase. If you opened the box, there’s a 10 percent restocking fee, but you won’t be charged the early termination fee if you also want to cancel service with AT&T. After 14 days, you can cancel your service, but you can’t return the iPhone. And after 30 days, you’re stuck with both the service and the iPhone.
