I vaguely remember some apps using the MAC address of the WiFi interface as an identifier. Has this been banned yet?

  Maybe yes maybe no, but either way that's not a good solution. iOS 6 - use vendor identifier iOS 5 - create an ID via CFUUIDCreate() and save it iOS 4 - can be safely excluded from support

    Vendor identifier is user-resettable. Storing UUIDs fails on reinstalls. MAC is persistent, as are other tricks like keychain storage
