Iphone screen locked up, no one has had this problem before. Please help me

You can try waiting for the battery to drain then connecting it to a computer that has iTunes installed on it. This should make it start back up with hopefully the apple logo visible. If it is still not working, your screen itself may have gone out.

Hope this helps.

Try to hold the home button and the power button down together until you see a white apple.

You can actually lock your iPhone so you can't accidentally use it. Well, i have this steps of solution that you need hopefully in can help you.
Find a button on the top called the sleep/wake button. The button's a tiny black button on the right side of the phone. It's not actually on the screen part of the phone, but on the silver part.
Press it and your iPhone will lock.
Unlock your iPhone by noting the locked screen. You'll see a small bar at the bottom of the iPhone with instructions to slide the bar to the right to unlock your phone actually on the screen.

Slide your finger along this bar to unlock your phone.
Remember, you can still get phone calls and text messages even when you've locked your iPhone.

Hold down the home button and lock button until I shuts off and restarts. This is calld a hard reset and can normally be used whenever an iPod touch or iPhone freezes up

connect to pc , switch off the iphone , hold down power button and home button for 10 seconds exactly ,leave power button and keep on holding home button until itunes detect after that update the iphone

you can try to reset it hold the home and the power button for at least 10 sec or until the ipod resets and shows the apple logo

Connect your phone to the computer and open iTunes. Hold both the home key and the power button until the iPhone turns off. Continue to hold them both for 5 more seconds. Release the power button but continue to hold the home button for 10 - 15 more seconds. I tunes should detect the phone in DFU mode. Restore firmware from this mode.

You need to a fresh restore of the iPhone. Hold down the home and power buttons together until the screen goes black. Then while the screen is still black, plug it into your computer WHILE holding down the home button.
At this point iTunes should detect your iPhone and tell you that you need to do a restore.
Hope this helps!
