BlackBerry App World, RIM’s answer to the iTunes App Store, is set to launch on April 1st. This will be the very same day that CTIA Wireless officially kicks off. Although many have criticized RIM’s price structure — the launch will be a good test of RIM’s true potential in both its relationship with third-party developers and its overall reception with consumers who are desperate for BlackBerry applications akin to those that are very popular on other major platforms.
