    So, I've been reading the forums and Google and I'm not quite sure what I need here to fix my problem. The device works fine, but the trackball no longer has the click "feel". The button pushes down and comes back up (and works) but the resistance and spring is gone. From the posts, I've narrowed it down to three possible needs:

    - New trackball
    - New click dome
    - New membrane

    The "click dome" seems to make the most sense, but I'm not sure from the posts if that applies to a model different from mine. Can someone clarify?

    Here's the dome that is more than likely the culprit: BlackBerry OEM trackball dome - Cellular Nationwide Network - Cellular Accessories - 3G, Sony,

    See the sticky thread at the upper part of the 8900 forum on how to disassemble your 8900.
