A boon for theft prevention (or a bust for the iOS device resale market), is the implementation of a new feature, as of iOS 7, by Apple called Activation Lock, which is an extension of iCloud's previous Find My iPhone feature. If you had an iCloud account configured with the setting on an iOS 7 device and it needed to be reactivated from scratch after a restore, the process would not have been able to proceed until that account's password was entered. This was felt to be a burden and a management headache for those who lent out devices regularly, but by some municipality's statistics, this alone reduced theft of iOS devices as they became practically useless.
