i just finished doing this after days of contemplating whether or not to...

turning my BB back on and seeing my trackball still functioning was the HUGEST feeling of relief.. i wouldn't have even cared if it was greasier than i started out with.

dont know if i'd go thru the trouble again, but i must say my trackball does feel cleaner/smoother. i found gunk caked on the inside of one of the rings.

be careful when doing this, i can see how someone can easily render their phone useless! but much thanks to the OP!
