OK, I just notice this this today. Does your screen on your storm move? If you put your finger on your screen and move it around, does the glass part move?
That's normal. The screen actually "floats" and you can feel side to side movement. This is done in support of the "clicking" mechanism. It really only moves when you put effort to move it. I've never had it shift as I'm typing or using the phone.
i'm worried about grit getting down in there, the gap is pretty wide and sooner or later it's going to gum up. I wonder why BB didn't design in some kind of membrane.
