I tried to track it by logging into Find My iPhone using her me.com address, but the phone is offline, meaning the arse who found it has switched it off upon finding it. There was a passcode, her daughters year of birth, but that'll be irrelevant now. We've phoned O2 and locked the IMEI number and SIM, but I take it they can still restore it in iTunes and use it as an heavy iPod touch. Her last memory of having it was in a taxi to work this morning, as her car is off the road. She's covered through her work insurance, but after reading some of the stories of idiots on here asking how to unlock phones they found, my blood is boiling. So if anyone in the Glasgow area finds an iPhone 4 with a pink silicone/plastic case on it, do the right thing!
