McAffee also said svchost.exe was a virus too....
I answered this same question over at RIM forums.
I'm sure it's possible as it just peels off. However, it can be difficult to get the 83xx devices apart as they have that sticky foam between the display and the front cover. I have disassembled a few of them and it's a real PITA. The piece of foam has to be replaced as it rarely comes off in one piece.
