Some images have been revealed to Berry Review showing BlackBerry OS running on an AT&T Fuze. The Fuze originally runs Windows Mobile, but with the “BlackBerry Application Suite.” This OS is based on 4.2.1 and has all of the features a real BlackBerry would have. You can do BlackBerry email, PIN messaging, calender, tasks, memos, and even BES syncing. However, there are a few draw backs. For example, calls can not be made through the application and are routed back to Windows Mobile. Also bluetooth, GPS, and Wi-Fi are not supported through the OS.
