BlackBerry DevCon, Research in Motion’s biggest developer conference of the year, kicks off today, October 18th, in San Francisco.  One of the big announcements at DevCon will be BBX, the next-generation, QNX based BlackBerry operating system that RIM co-CEO, Jim Balsillie, said will leapfrog the competition.  DevCon Starts at 8:30 a.m. PST so we expect a bunch of press releases to start coming out at any time.
