my screen say "iPHONE is disabled connect to itunes what happened?

The main reason for your problem is that someone has entered an incorrect password for the phone several times.

The good news for you is that it isn't hard to solve.

I would recommend you put the device into DFU mode (search google on how to do this) and restore through itunes. Let me no how you get on

Thanks Tony

You don't need DFU mode, simply follow the directions here:
