For what I know, this is link to the newest Radio ROM available (2.71.11).
In the thread it's written it is g4 safe.
So I think you can flash it to your device plain and simple.
But I am not pretty sure if you need to use the RUU provided or the Mun's RUU from the Hard SPL thread...
EDIT:
I have flawlessy performed Radio upgrade to 2.71.11
I can now confirm it's g4 safe... just start the romupdateutility and follow the instructions...
No need to change RUU from the one included in rar archive for my G4 HardSPL.
