WATERLOO, Ont. - Research in Motion is hoping to give Apple Inc.'s iPhone more of a run for its money.

The Waterloo, Ont.-based company launched its latest smart phone on Wednesday with the release of the BlackBerry Curve 8900.

RIM has added an enhanced multimedia player to its popular BlackBerry, making the unit capable of airing podcasts. The phone also features a built-in global positioning system and an updated camera.

RIM has had to contend with stiff competition from Apple since the U.S. software giant launched the iPhone in Canada in July.

Apple sold 6.9 million iPhones in its fourth quarter compared to the 6.1 million BlackBerries RIM sold in its quarter ending Aug. 30.
