BlackBerry is continuously updating their great Beta Zone app for BlackBerry 10. I really wish BlackBerry would put more of their apps and even OS updates in the Beta Zone but currently it is useful for BBM Channels. The latest update to the app includes a feedback form and the ability to capture some device details like model, pin, and OS version. They also threw us a bone with some performance and UI improvements.
Check out the update here. Thanks TT for the tip!
