iPod Locking

If you have an iPod or indeed an iPhone and you use the "Passcode Lock" feature then you could be in for a shock if you forget your password or PIN code......so you have set the passcode and you have tried to unlock you iPod/iPhone by sliding the slider to unlock.....then you need to enter your Passcode....
So you enter it wrong 5 times and you get locked out for a minute, after this time lapses you are able to enter your passcode again, get this wrong again and you get locked our for a little longer....
