The BlackBerry still holds a majority lead in the corporate space but is losing ground to the iPhone at smaller shops, TNS found on Monday. Among all businesses, the BlackBerry had 69 percent of the US but saw its share drop sharply outside of big companies. Enterprises with 1,000 or more staffers were dominated by RIM's 81 percent share, but the iPhone now had 35 percent of small business, or twice as much as it had overall.
