My wifes iPhone 5 is lost and was probably stolen. She left it behind in the restroom of a very reputable hotel, where she was holding an event. Less than 20 min later it was gone. While it was low on charge, it should have had enough left to respond to Find My iPhone about two hours later, when we was able to turn her attention away from the event. At that point I was unable to track it with the Find my iPhone app on my phone. This could have been, because the charge did run out, or because the person swiping the phone took out the SIM card immediately. With the phone running iOS 7 and Find My iPhone having been enabled, it also had Activation Lock turned on. What can thief do with this phone at this point, as it is essentially bricked?
