Good news for all you devs and user agent investigators. I personally browse through the user agents on a daily basis on the BlackBerry Empire forums to check out what devices, OS, etc are accessing the forums. Great way to find out who is on your site and what are they using to access it.
Check out the user agent code explained below:
Mozilla/5.0 (BB10; <Device Model>) AppleWebKit/<WebKit Version> (KHTML, like Gecko) Version/<BB Version #> Mobile Safari/<WebKit Version>
