Previously in the actual Beta Zone, and now released in to BlackBerry World is the Beta Zone client. Before this app, if not on a Legacy device, you had to sideload all of the new beta’s which was a little annoying. Then you would have to cut and paste the long Keystring in to the Terms and Conditions box to be able to use it. Now it seems that is all in the past. With the new Beta Zone app, with just a simple click it installs the newest beta on your device with no hiccups. Now it does not allow you to sign up for new programs what I have seen from within the app, but regardless this is a well welcomed app.
You can get yourself your own copy from BlackBerry World, and make sure to verify that you are a member of the Beta Zone if nothing shows up in the app. Please note that at this time, this app is only available for BlackBerry 10, as Legacy devices and OTA right from their browser.
