I notice on the tablets-dev.nokia firmware download site that there is a UK firmware for the 42.11 build:

RX-51_2009SE_1.2009.42-11.203.2_PR_COMBINED_203_ARM

But for the PR1.1 update there is only firmwares for USA, Middle East & North Africa and Global.

Am I correct in using the Global firmware to flash my UK N900?

If I use Nokia's NSU will that flash using the Global Firmware or does NSU have access to a UK variant?
