BlackBerry 10 Dev Alpha owners get a treat today in the form of a new OS update. OS version 10.0.09.2320 has been made available OTA and via the update page for PC users. We're not sure what's new and exciting in this one, so if you come across anything be sure to hit up the comments and let us know. Just think -- in a few weeks everyone will look forward to the BlackBerry 10 updates! :-)
