After 10 tries it completely locks you out and you have to call your wireless carrier to get the PUK code to unlock the phone and reset your PIN number.

If the PIN is not locked, then it's a delay and it should be unlocked after some minutes.

There is no textbox to type PUK code. I have waited about 1 hour but no change, only an apple on the screen.

** NOTE ** It will perform a reset..

1) Hold buttons sleep + home untill iPhone turns off;
2) Open iTunes;
3) Hold home button and plug the phone to your computer. The phone will turn on and the iTunes + Arrow + cable screen will appear.;
4) iTunes will recover you phone from unsuccessful recovery process.

If you have paired the iPhone up to an Exchange server and the Administrator has enforced a PIN for security, then having entered the PIN incorrectly several times, the iPhone will have been factory reset (all data . settings erased / set back to how the phone was when it came out of Apple's factory).  It won't be a case of getting the PUK code from the Airtime Provider.

As the phone is showing the Apple logo - you need to pug it into a computer with iTunes on it (preferably the computer of the owner of the iPhone) and set it up / recover the data from the backup which they have hopefully taken.

If they don't have a backup - they will have lost everything.

I will keep my fingers crossed for you.

Oh well - thank heavens for backups!

We had a customer that had the same problem - only no backup - so you are doing well.
