With the exception of our BlackBerry Curve 8520 giveaway, we've been lighter than normal on contests this week. For some last minute weekend fun, the good folks at R&R Theme Designs are offering up 50 free copies of their SlideBerry Zoom theme. This clean theme features custom icons, signal meters and customizable homescreen icons. Available for the Bold, Storm and Curve 8xx series, SlideBerry Zoom normally sells for $5.00 at the CrackBerry App Store. Leave a comment on this post to be entered to win one of 50 free copies. Contest ends this Sunday at Midnight PST - please leave only one comment, multiple submissions won't count.
