The Blackberry 8820 is very similar in design and specification to the 8800, however a major advantage to the 8820 is the Wi-Fi capabilities.

Like many other Blackberry’s on the market, the 8820 features the light sensitive, 65K colour screen that adjusts itself to the ambient lighting levels so it is easy to use both inside and outside.  It also has the Trackball navigation system, a full QWERTY keyboard, and Blackberry Maps. 

The phone comes with 64Mb of flash memory, and this can be expanded using a microSD card, and Bluetooth technology which can also be used with a Bluetooth headset or a Bluetooth car kit.  The 8820 also comes with Wi-Fi wireless connectivity and EDGE technology for high speed data transfer, but it is not 3G capable.  It does not have a camera either.

Some  additional features in the 8820, are a music player, HTML internet, voice dialling, speakerphone and the usual organizer applications such as a calendar, alarm clock etc.
