OS PSR 9000Pro

Hi,
anybody outside who knows, if the OS-Update 2.1 for the 9000 works in the 9000Pro too, or ist this a new OS?
Thanks for help.
Herbert

Hi Herbert,
as far as I understand, does the 9000pro start with version 1.0 wich is the same or higher as 2.1 from the psr-9000.
I red this on the german forum from 9000pro owners.
Hope this helps.
