[ PDAs & Handhelds ] Open Question : My Blackberry Curve 8520 trackpad keeps getting suck?!?

I have a Blackberry Curve 8520, the one with the trackPAD not the track ball. I had one that I loved, but the keyboard malfunctioned so TMobile sent me a replacement. On the replacement phone the trackpad always sticks. And I dont mean like "freezing" or anything technical. Its just really hard to press when I need to click something. It took like 3 days for me to reconfigure my BB after receiving the new one, and would really rather NOT go through all that again by requesting another replacement. Any sugguestions?? Thanks!
