The executive also pointed out that the operator was offering the new iPad for $0 down with its AT&T NEXT plan. With NEXT, customers pay for a device monthly, and after 12 months, you can trade it in for a new phone or tablet. Despite the increase in activations, there are probably still quite a few AT&T customers waiting for the Apple iPad mini with Retina display. Demand has been building for the sequel to the 7.9 inch iPad mini, but Apple has delayed the release of the tablet. The Cupertino based tech giant has had trouble obtaining enough Retina display panels as it attempts to build enough tablets to catch up with what almost certainly will be pent-up demand for the device.
