Hi all, I charged my iPhone normally and I recognize once I disconnected that a white bar appers at the bottom of the screen, covering all the bottom text.The iPhone touch works even on the bar, so I don't think is problem of Death Strip.I've tryed to restore but it doesn't works.If I try to move an icon over the bar it goes underneath.The bar is also displayed at the boot so I've tha Apple logo the black screen and the bar at the bottom.Any idea how to remove it?

Many Thanks
