While it has not been officially announced to the public yet, member from Motomodding UK forum has found the ROM upgrade software (SHIP_NORMAN_AP_U_01.09.28R_MODEM4_U_40.11.40R_04_U). The upgrade process is not quite straightforward though, you will need to make use of the RSD Lite 4.1 software to upgrade the ROM. Read through the discussion thread for the detail.

There should be an official announcement and instructions to be made soon, if you can wait .. Check out the thread here
