Developers complain about the complexities of building for BlackBerry, and many corporate users are blocked from downloading available apps. As we did with our Best Android Apps, we've wrangled the best free and paid apps for BlackBerry. The BlackBerry App World was launched about a year ago, marking RIM's reaction to the robust iPhone app store and a move to try and keep RIM's non-business user base RIM from switching to Apple or one of phones running Google's ( GOOG) Android. Our experience in building TheStreet mobile for BlackBerry was great as our developer and a representative from RIM worked together well. Yet unlike working with the folks at Google on our Android app, RIM doesn't offer developers a review or critique of the app to make sure it takes full advantage of the OS. Apps will be one of the factors in the health of a company's OS going forward; RIM would do well to get more involved and follow Google's lead. This look at free and paid BlackBerry apps is by no means complete -- new BlackBerry apps come on line all the time. Please comment and give us your reviews and opinions.
