I am not certain, but I believe that most manufacturers have adopted the standard pin-out on a USB Mini B connector. I connect my BlackBerry to my PC using a Belkin cable that has also been used to connect numerous other devices.
Out of curiosity, doesn't your Curve have GPS? My 8330m does, and once I corrected its settings, it is pretty sweet.
