I have a lady friend who lost her Iphone 5 two months or so ago. It is safe to assume that the battery died that night (it was already low and it was very cold that night). So she could not track it after that night. Assuming the worst case scenario: i.e. that the phone was found, they removed the SIM card and restored it and now they are using it ONLY as an Ipod Touch. Can the phone be tracked/located when they connect via WiFi to the internet OR use iTunes by using the IMEI number (or serial number)? Would the GPS help with that? Thanks.
