what is the radio

I know somewhere there will be an answer for this but I haven't been about to find it.

I was wondering what the radio part of the ROM was ie you must update the radio. I see everyone talks about it but no one says what it is.

The reason I ask this is that some ROMs are classed as safe as they don't touch the radio where others do. I would have thought the Radio was the part of the phone that makes the calls and normal ROM's are the PDA side but I posted a message to a guy who made a changes to his phone where he said his radio was working but he was able to make calls data and text. So I'm lost.


If anyone else has done this, my intent is to flash DCD rom and radio to a New Zealand mobile, my understanding is our phones are the same as sprint
