I lost my iphone 4s and had to get a new one. when I found my old one it had been run over. It powers up, but the touchscreen wont work at all. It is password protected and I just want to get my pictures off of it. When I plug it in to my computer, Itunes tells me the phone is locked and needs me to enter the password into the phone. I know the password but have no wat to enter it. Any ideas?
