Research In Motion ( RIMM) believes that it's time you "prepare to enter a world of possibilities." As of today, the new application storefront for BlackBerry users has officially been announced -- and named. RIM is asking that those interested end-users as well as developers begin registering today for the new "BlackBerry App World." The new store will join Apple's ( AAPL) iPhone and Google's ( GOOG) Android online offerings as well as a proposed store from Nokia ( NOK) (Symbian OS). RIMM really seems excited about this new feature. In its own words: "Find tons of great applications designed for your BlackBerry smartphone in one convenient place -- BlackBerry App World. Personalize your BlackBerry smartphone with games, social networks, personal productivity applications and so much more. Message your best friend, track the stock market, or channel your inner rock god. Sign up for BlackBerry App World today and discover how to put more of your life on your BlackBerry smartphone" To use App World on your phone, you will need to be running the BlackBerry smartphone operating system 4.2 (or higher). It is said to work on BlackBerry smartphones with trackballs (Bold, Curve, Pearl, and Flip) or a SurePress screen (Storm). That means the new download store will work on any modern-day BlackBerry. RIM isn't saying a whole lot more about its new app store except that it'll be accepting PayPal for software purchases. Developers from all around the world are being asked to begin submitting applications to Research In Motion for approval. They're looking for both consumer and business-focused programs. According to RIM: "The market for BlackBerry applications is growing at a phenomenal rate, and the BlackBerry App World will offer you (developers) the exciting opportunity to showcase your applications to millions of BlackBerry smartphone users. It will provide consumers with greater choice and enhanced application discovery." RIM says it is currently counting down to a BlackBerry App World launch this spring. TheStreet.com will be a part of BlackBerry's new App World, but you don't have to wait a second longer. Right now you can download and install TheStreet.com Mobile on your BlackBerry device at m.thestreet.com.
