For some time the touch screen on my wife's iphone has been sending comments racing up and down, so it’s difficult to read anything. The brain dead creature we spoke to in our local Vodaphone shop insisted that Vodafone couldn’t help - because it is a software problem??? and we would have to go home, update everything, then do a backup and restore, which we did and the problem is still there. The touch screen is not responding properly.

Has anyone else experienced this?
