The BlackBerry Curve 8520 is an enterprise-based smartphone (as all Blackberry devices) and has standard features including mobile email, calendar and instant messaging amongst many others.
The BlackBerry Curve 8520 has a new Touch Sensitive Optical Track pad Key feature as opposed to the standard Joystick used on many other BlackBerry devices -this is said to improve the ease of scrolling through menus, emails, Internet browser, and images as it is an optical sensor rather than a series of closely spaced buttons.
The BlackBerry Curve 8520 was discontinued in April 2012, when the BlackBerry Curve 9220 was introduced as the successor to the BlackBerry Curve 8520.
