Well, it looks as if Twitter isn't the only one announcing something beta-related today. BlackBerry has (quietly) released Beta Zone for BlackBerry 10, an application geared toward folks who are game to try stuff before it's ready for prime time. The firm's newly outed app gives members an easy-to-access hub where they can download the latest software arriving on the platform in beta. As you'd expect, Beta Zone for BB10 won't cost a dime to download, though you will need to have an account before being able to access any of those rough-hewn apps.
