A few weeks back we checked out Call Blocker Professional from Epic Applications. The response was overwhelming, and the app is topping the charts in both the CrackBerry App Store and BlackBerry App World. Call Blocker allows you to easily block numbers and better manage your incoming calls. You can block area codes, specific numbers, whitelist your contacts and even set "quiet times". Call Blocker Professional fully integrates with the Options screen and helps you take back control of all your calls. From now through January 12th, you can pick up Call Blocker Professional for $1.49 (regularly $5.99) in the CrackBerry App Store.
