Dumb question probably, but.. what is the "radio" (is it the FM radio app?)? and why does it apparently need to be updated separately?

As i understand it. Its a combination of hardware drivers and the part that gives you connectivity to cellular networks.


It has to be updated seperatly because its not part of the rom. But highly hardware specific.

Alright, thanks for the explanation. So as far as I understand, this is something one should only update if he/she is experiencing any issues with the device, right? Or do I get new features/faster speed/longer battery life when I update to a more recent radio version?

The eternal questions: what's the best radio? and what's the best RIL? Usually, the best ones are the ones which come with the stock ROM. In the case of the HTC Desire, the radio version is 32.56.00.32U_5.17.05.23 and the RIL is 2.2.0028HM. I have tested this combination with the nightly 182 and it worked well. Now, I have the nightly 215 and I changed the RIL to 2.2.0018G and it works well in this combination too! Concerning the RIL, one only needs to change the libhtc_ril.so in /system/lib. Nothing else.

That's the RIL. It is part of the ROM.

That's the radio firmware. You are right about this not being part of the ROM. It is usually updated with the fastboot tool (in case your phone was S-OFF-ed). I can be updated through the recovery, but in my opinion it is more delicate (a good script needs to be written or the right recovery for the script needs to be used   ).

Hello Tulpix,
i did some research on the net and according to what i've found so far, there is nothing like a "best radio for ROM xy". The radio firmware controls your GSM/CDMA antenna, wifi and bluetooth and is released by the phone manufacturer for the specific phone models. So basically different radio versions can (some say they can not) vary in better cell signal coverage, better wifi coverage, longer (or shorter) battery life and so on. Unfortunally it seems that there is never any changelog provided with the radios.

greetings,
toco

Ah, someone wrote in the same moment as I did.
So, just to sum things up Alx MAX - the RIL are some kind of hardware drivers for android and get updated with each ROM update (in my case CM7.0.3->7.1.0)? But you also CAN update the RIL manually? ("... changed the RIL to 2.2.0018G and it works well in this combination too!")

I would not call it driver. The RIL consists in a daemon and some shared libraries. CyanogenMod comes with an AOSP RIL (the same as Nexus One) which is quite old, 1.6.xxxG. You can change it and you only need to change /system/lib/libhtc_ril.so. The other components of the RIL do not need to be changed. When you search for a RIL, the rule is the versions which end with a G are for AOSP and the versions which end with HM are for the Sense ROMs. As I have mentioned, I have tested both a Sense and an AOSP RIL and they both worked but I haven't used some advanced program to see the differences. Just daily use.
