Research In Motion disappointed investors with solid -- but not spectacular -- numbers for its first-quarter earnings yesterday, but analysts are still bullish on the BlackBerry maker.

RIM's (NASDAQ: RIMM) adjusted earnings of $0.98 per share topped Wall Street expectations by four cents, the company reported a 53 percent jump in sales to $3.42 billion, in line with analyst estimates. But RIM's 3.8 million new subscribers came in just below expectations.

Yet the company still posted a number of positive figures, as well. During the quarter, RIM shipped approximately 7.8 million devices, and the total BlackBerry subscriber account base grew to approximately 28.5 million, according to RIM.

"We are starting fiscal 2010 with strong financial performance and impressive market share gains, including a 55 percent share of the U.S. smartphone market according to IDC's latest estimate," Jim Balsillie, RIM's co-CEO, said during the company's earnings call. "The industry-leading BlackBerry product portfolio is driving strong customer demand around the world and our penetration of new market segments continues to expand."
