Today the CrackBerry Deal of the Day is a great application at a great discount. Tetherberry made its name offering an easy and affordable way to tether without the need for extra services or carrier fees. The application usually sells for $49.95 which is a turn off to some users, but today only you can get Tetherberry for only $24.97 - thats 50% off! This is a great discount if you've been contemplating pick it up but just haven't pulled the trigger. I've been using it on my netbook since release, and I must say there is no easier way to tether. Just install the app on your device and PC or Mac and you're set. Head over to the CrackBerry App Store to check it out.
