The exterior of the new BlackBerry 8820 may look familiar. After all, the device has the same sleek black design as the BlackBerry 8800, which was launched earlier this year. The new phone has one important upgrade under the hood, however: Wi-Fi.
This is the first BlackBerry with Wi-Fi support, and the addition is a welcome one, as it means the phone can provide wireless voice and data access over both cellular and Wi-Fi wireless networks.
In addition to Wi-Fi, the quad-band GSM phone includes support for the carrier's EDGE network--but not its true 3G HSDPA service.
