It looks like a very early BlackBerry 6 copy was leaked and installed on the CDMA BlackBerry Bold 9650. Since this is an early build, things are a bit choppy, but the OS runs fine on the non-touchscreen Bold 9650 with its 512 MB of RAM and ROM; the GSM Bold 9700 may not fare as well with its more limited 256 MB of RAM.

BlackBerry 6 debuted initially on the BlackBerry Torch on AT&T, which shows RIM’s focus on the touchscreen environment, though the OS will work on non-touchscreen devices as shown on the video.
