Updating the look of the Curve with a sleekly styled titanium finish, the BlackBerry Curve 8900 is the thinnest and lightest full-QWERTY BlackBerry smartphone yet. In addition to its stunning good looks--with titanium-colored finish accented by chrome highlights--the Curve 8900 is packed with communication and location features. The built-in Wi-Fi (802.11 b/g) supports both voice and data, while the built-in GPS supports location-based services including turn-by-turn navigation.
