RIM announced the launch of a dual mode Blackberry, which will operate on both GSM and Wi-Fi networks. The new Blackberry 8820 will launch on the AT&T network. It didn’t take long for RIM to get this new device to market. We reported about the FCC approval of the Blackberry WI-Fi device on July 9th. The new 8820 Blackberry also supports unlicensed mobile access (UMA) technology, which allows for seamless roaming between GSM and Wi-Fi. Although AT&T’s plan for UMA are somewhat unclear at this point. AT&T is expected to bring the 8820 to market later this summer.
