Just had my iPhone 4 stolen during a work do (of all places). As soon as I realised that someone had lifted it from my pocket I used the hotel computer to initiate remote wipe, however, it appears the low life scum have already turned it off, so the wipe is pending. How safe is my data on the phone? Can they get anything off it without turning it on? Or if they take out the sim and put in another one, can they access my data? A little worried at the moment as my phone insurance company don't have 24/7 phone lines so cannot block my phones IMEI number. Help?
