Q: Iphone 4: Bottom-right hand side of screen doesn't work so I cant slide to unlock...anyway around this?

Bottom right hand side of my phone is not responding. I restored it but cannot complete the slide to unlock due to the unresponsive right hand side of the screen. Is it possible to by pass needing to complete the slide to unlock just to receive phone calls and text messages? Or what do u recommend me do to fix the problem?

Thanks in Advance
