Hey so I had an AT&T iPhone 5 for less than 30 days. At the time I was eligible for an upgrade through AT&T. I took back iPhone today to the apple store and got a full refund. However I would like to purchase another phone from AT&T does anyone know how the whole reversal upgrade status work? My status still says I'm under the iPhone 5. How long do I have to wait for my status to reset since I returned the iPhone 5.
