With Apple raking in millions of dollars each month from its iPhone and iPod touch App Store, itís no wonder that others are ramping up their competing services. One of them is BlackBerry-maker RIM, which announced their intentions to launch an on-device application distribution hub late last year, and just yesterday sent a notice to developers that they are now taking submissions for this new storefront.

Although there are many apps already available for BlackBerry devices, the Application Storefront will provide a central service where users can quickly browse, purchase, and download new software for their handsets. We donít know exactly when the new store will officially launch yet, but many expect it to go live this spring. If you are a developer, check out this site to get your application in Ė provided that it passes the internal review process.
