We know Apple and Android are having all the application fun right now, but don't rule BlackBerry out just yet. Storefront, RIM's answer to the iPhone's App Store and Android's Marketplace, is scheduled to launch sometime in March. The company's already started taking submissions from developers, so we're expecting a number of choice apps to be ripe for the plucking. Until that times rolls around, here are a few handy apps to help you personalize and customize your BlackBerry with features you can't get anywhere else. We've already listed the best free apps for this manufacturer, so below you'll find five of the best paid programs for your RIM phone. The prices start at $4 and rise from there, but we assure you, each one is worth the ding to your wallet.
