Under the bonnet, the Curve 3G will ship running the BlackBerry 5 operating system. However, RIM has confirmed that the 9300 will be upgradeable to BlackBerry 6 in the future. The company declined to reveal precisely when the OS upgrade will be available, saying that it will be available "in the coming months."
BlackBerry 6 OS offers an overhaul of version 5 and includes a redesigned home screen, new contextual on-screen menus and a significantly improved browser. The new OS will make its debut in the BlackBerry Torch 9800, which was announced last Tuesday.
