Hey all,
I have a Japanese SPH-DA09 unit, that seems very similar to the SPH-D100, however this unit has built in DTV and DVD/CD player, very much like the SPH-DA210 unit released in the US, however it is not a SPH-DA210 in that the firmware revision for it is based on the NX163 code, the same as SPH-D100, which makes sense because the DA09 is the upgraded version of the DA05 which is basically identical to the D100.
As a test i flashed the D09 with the D100 SYS yuk file and the unit basically acted exactly the same as a D100, english menu, no DTV option, language options in settings etc,
