Please Help: iPhone troubleshooting

[Maniamac]

My iPhone's screen has become completely unresponsive. I've held in the power and Home buttons for ten seconds; that didn't work. I've restored the phone; that didn't work, either.

Has anyone else had this problem? If so, are there no other troubleshooting tips?

Thanks.

Did you...

jailbreak or unlock the iPhone?

Thanks for the reply.

No, I haven't. Guess I'll have to bring it in, then....
