Are the firmwares available through SE Update service the same as

I currently have a P900 with the CDA of 162004/29. According to the SE
Update Service, the current firmware is R3A06.

Does anyone know if a later version is available through EMMA (or
whatever the S/E official service point updating system is now called!)?
Ie, if I go to a service point, is there a later version they can give
me, or am I stuck on R3A06...
