Keypad? Do you mean the virtual keypad on the iPhone screen?
By "hard restart", do you mean you've pressed the home and on/off buttons simultaneously for at least 7 or 8 seconds? Does the machine then start up normally, only unresponsive to your keyboard commands? If that's the case, you can start applications (like the weather widget), right?
If all that's true, have you tried powering your iPhone off, then restarting? Have you tried restoring it?
Yep I have tried restarting it many different ways with different time sequences. The middle and top button work just fine, The front touch screen does not work (the slide will not slide open and I can't type in any numbers) I dont want to restore it becuase it will delete all my contacts, pictures and apps. All I want to do is unlock the key board to back up my iphone.
Ah, so it sounds like you've not backed up your iPhone before. (If you had, you could restore its software and then reload its backup, which would reload contacts, photos, apps, etc.)
So if that's true, I don't know what to suggest, other than suggesting you perform backups in the future.
