1: Make sure firmware is up to date
2: Disable Wi-Fi when not in use
3: Disallow automatic association to networks
4: Turn Bluetooth off when not being used
5: Disable location services until needed : Turning location services off doesn’t immediately increase security; it just prevents the user’s location from being published.
6: Set a passcode
7: Erase data if too many wrong passcodes are entered
8: Erase data before returning or repairing the iPhone
9: Disable SMS preview: Even when the iPhone is locked, it’s still possible to preview a recently received text message.
