Needless to say the BlackBerry Curve 8300’s main feature is its full Qwerty keyboard. Trackball fans will be pleased to know that the traditional BlackBerry trackball makes a return here, despite other BlackBerries introducing optical trackpads. The media player supports a wide range of music files and there’s that all important 3.5mm audio jack. The 8300’s memory can be upgraded with microSD cards. Other features include GPS and a 2-megapixel camera with flash.
