The dual-mode BlackBerry 8820 was announced Tuesday by Research In Motion Ltd. Named "dual-mode" because it works with both the EDGE/GPRS/GSM cellular and Wi-Fi connectivity for data access and voice support. The Wi-Fi connectivity will allow users to connect off of the cellular network, at home through 802.11 a/b/g wireless networks, and through Wi-Fi hotspots. The 8820 is RIM's first dual-mode BlackBerry, and it's said to be the slimmest Blackberry to date. "The BlackBerry 8820 is an extraordinary business phone for people who really care about mobile communications and productivity. It features all the renowned power and usability of the BlackBerry platform with executive class styling and unprecedented connectivity features, including cellular, Wi-Fi and built-in GPS," said Mike Lazaridis, President and Co-CEO at RIM.The phone will be available in the US through AT&T, a Canadian carry is yet to be announced. As the news broke RIM shares climbed $4.19 to $240.29 on the TSX.
