NO!
Please I beg you never take off your screen. I know from experience. Just don't do it... Although I hear on the 8310 it is easier to go through the earhole without breaking it.

My LCD lens broke when I was trying to take it off, than it did not seal back on right when I ordered a new one, resulting in way more dust getting under, and ultimately it cracked. Taking off the LCD caused ALL my problems.
