Something to try. You say you keep your phone in your pocket? I'd bet it has collected lint, etc in the area on the edge of the screen. Use a thin object like the edge of a buisness card to clean out areound the screen with possibly a good blast of canned air to make sure you get it all. This is a common problem with the Apache having touchscreen issues due to dirt and debris in between the case and edge of the screen.
