Gemblock is holding a custom BlackBerry theme competition where a $100 prize will go to the BlackBerry theme builder who submits the best original BlackBerry theme.
Votes will be based off of:
All submitted themes must work on either the BlackBerry Pearl, BlackBerry Curve, BlackBerry 8800, or BlackBerry 8700 series devices.
Voting starts on January 1st, so, if you are interested you have a little over a month to work on your theme.
