In a nutshell : The BlackBerry 8800 is packed with a wide range of communication features, including phone, email, instant messaging, GPS, maps, web browser, a wealth of personal organiser functions, and even a media player. It's the most businesslike of the BlackBerry series, but lacks 3G and WiFi.
The BlackBerry 8800 is the same as the 8820, except that it is missing WLAN. Read our 8820 review for a full description. The BlackBerry Curve 8900 updates the 8800.
