As many trackball bearing users know, especially BlackBerry Tour 9630 users, the BlackBerry trackball is a magnet for lent and dust and tends to get gummed up from time to time preventing you from scrolling in all directions freely.  This video shows you the quickest and easiest way to fix your BlackBerry Trackball, that from what I’ve heard, works most of the time.

If this doesn’t work, you can always replace your BlackBerry trackball, however, I would give this shot first as it may definitely save you time and ten bucks.
