If you can't get enough of BlackBerry OS 10.3 and want to some more of it then you may want to check out this quick hands-on with 10.3.0.296 from ZonaBB. Overall, it shows off a lot of what we already know is coming but it's still nice to see in action. No telling if and when it'll leak but the folks at ZoneBB have noted they'll be, at the very least, showing off some more of the OS in the near future.
