Dear Friend,
Type the wrong password three times and it will ask you for a PUK Code.
Contact your service provider and they will ask you for a PUK code. Enter that in the cell phone and it will unlock the cell phone .Go to the security settings and disable the security.

That Should Do!!

yep that same exact thing happen too me, what u have too do is probably go too a phone store and get it reset or unlocked and then ask them too put a password and u will be set

I think the your screen may have given up due to long use or due to miosture. This may be fixed by changing the LCD sreen from your mobile's authorized dealer.
