Does anyone know if att replaces defective phones in house or if i have to send it away. The SIM slot on my phone no longer reads SIM cards and I was hoping to walk out with a working phone after they realized replacing the SIM card won't help. I have owned the phone for a total of 43 days so I know I'm out of luck for the 15 day exchange, and coming from iPhones I'm not sure how it would work with att.
