A video of the, yet to be officially announced, BlackBerry Curve 9300 is making its way around the web. As most BlackBerry Curves to come before it, the 9300, code named Kelper, appears to be a pretty solid device. The BlackBerry Curve 9300 is definitely still in pre-production. It only runs a version of OS 5, however, we imagine that this device will be upgradable to BlackBerry6 if it doesn’t come out of the gate with it.
