Motorola and Sprint are rolling out a system update to the Motorola Photon 4G. Chief among the changes is support for Google Talk with video chat. Photon 4G owners will be able to conduct live, two-way video chats with other Google Talk contacts once the update is installed. Other features added to the Photon 4G include support for Motorola’s LapDock accessory and webtop mode; improved in-car audio quality; improved performance of the panorama shooting mode; and the introduction of international roaming 3G UMTS hotspot functionality for a single Wi-Fi device. Instructions for installing the update are available from Motorola’s suport site.
