While the weak economic climate has most tech stocks sucking serious wind, BlackBerry maker Research in Motion is on a tear. The Canadian company reported that sales and profits more than doubled in the fourth quarter, comfortably beating analysts' expectations. The full fiscal year revenue was $6 billion, up 98 percent from 2007, while net profit was up 102 percent to $1.3 billion. The company also expected first quarter results to be much better than expected. The good news drove RIM shares up 5 percent in after hours trading.

Investors have been buoyant about RIM since the company announced in late February that net subscriber additions would be 15 to 20 percent higher than previously expected. In the end, RIM hit the high end of its new growth range, reporting 2.18 million new subscriber additions in the fourth quarter. The company now has more than 14 million total subscribers.

The first quarter looks even rosier for the wireless giant: sales are expected to be between $2.23 and $2.3 billion, trouncing expectations of $2.02 billion, while earnings should be between 82 cents and 86 cents per share, again beating Wall Street's estimates of 76 cents per share.
