Popular online storage solution Dropbox has just launched its BlackBerry client as a limted beta. The app, compatible with OS 5.0 devices, already was gobbled up by the 500 user slots for testing. Those that snagged a copy are reporting that the application is similar to the Android and iPhone client, but is still missing some key features like the ability to upload non-picture files, the ability to delete/move files, and the ability to manage folders. BlackBerry owners that are interested in the beta should keep checking the beta site as additional slots are apparently being added to meet this initial demand. If you manage to get in on the beta, hit us up in the comments with your first impressions.
