Hey all, Before I go and swap for 4th iphone what do you all think about this. I was on vacation for the last 10 days, On a cruise, no cell-sites or communication and far out from civilization. When I came back, my phone would no longer make phone calls. It will get them and be able to get txts however outgoing calls will not work, internet however does. I swapped the sim card into another phone for now. The att rep. said he had no idea and said it is 100% weird considering the phone was working prior to being left in a safe for 10 days. I tried restoring the phone 3 times varies different methods, the phone was not jailbroken nor tampered with in anyway (Good ol' vanilla.) Any ideas??
