Nope, not the 1052, it was the first thing I looked for, it was actually a .296 – the device is just for carrier tasting, I guess only BlackBerry staff gets the brand new updates ;)
About the frames - I asked the person how to make them smaller and they said it works automatically once you open more apps. But again this wasn't the final OS and the person wasn't working for BB, so I didn't get any future features insights. The carriers don't even care about the OS or things like audio output, from what the person said they only test whether the carrier's network features work fine on the device.
