I heard it before, but according to Macrumors forums users are reporting a “dead strip” on the iPhones touch sensitive display. This “dead strip” is an area on the display that does not allow any gesture input. I seems to only occur be only at the bottom or top part of the display.

One forum user reports: ”First the very bottom of the screen went out so I could not hit the space-bar on the keyboard, or change to the number/character screen. Then it got worse a few days later, now I cannot hit any of the main function buttons.”

Nothing like restarts or reboots seems to dissolve this problem. Firsr rumors say it is a hardware problem of the iPhone that the display is not responding to finger input. It also seems like that Apple is aware of the situation and exchanges displays that are broken and don’t respond any more in the “dead strip” area.
