It's almost March and that can only mean one thing, CrackBerry's 4th Birthday. To celebrate, the good folks over at SOTI, Inc. are having a 50% off sale from now until Friday March 4th. I'm a big fan of Pocket Controller-Pro and how it packs ten features into one small package. It's a pretty cool BlackBerry and PC application that lets you control your device using only your mouse, monitor, and keyboard. More importantly, it means you can access BBM from your desktop. If you've been waiting to purchase because of the $35.99 price tag, then now is the time to visit the CrackBerry App Store and take advantage of this offer.
