After iTunes not wanting to restore my iPhone, I decided to use the now free, Find My iPhone service to remotely wipe my phone ready for my appointment at the Apple Store. After initiating the wipe I received an email saying it could take up to 2 hours to complete, my appointment being within the next hour didn’t help. Unfortunately I arrived late to the appointment, but my phone still hadn’t wiped. After not being seen I needed to use my phone again and it states in the email that you cannot cancel the wipe, however a hard reboot stopped the process and nothing had been deleted, within the hour that it was apparently wiping. So this displayed a massive flaw with the service to me, if a person was to steal a iOS device that was then remotely wiped, the theif could simply hard reboot the iOS device and have access to everything.
