Radio version numbers .10 vs .00 (or .11 vs .01)

[ma499]

Has anyone yet figured out what the penulitmate digit in the radio version numbers means?

Looking at the list of published ROMs on the wiki I can deduce the following:

- Asian and generic WWE (which I assume originate from Asia) ROMs use .10 or .11
- O2 used .10 for WM5 but now .00 for WM6
- All other (European, North American) ROMs appear to use .00 or .01

Are they optimized for different network parameters? Is there some major difference in network standards between Europe/North America and Asia?

I believe that .11 (or .01) means that GPS is enabled.

correct .11 radios are for the trynity since it has GPS the Hermes has the same chip but the GPS has been killed in it people have tried very hard to gert it to work but its a no go.

Yes, I've seen elsewhere the at the last '1' indicates GPS support. I'm still curious to know what the penultimate digit (i.e. .1x vs .0x) indicates. As far as I can see from the info on shipped ROMs there is a geographical bias. Perhaps we ought to be bearing this in mind when choosing radio ROM versions?
