They package the modem/controllers on the S3, but the actual radios (of all kinds) are on separate chips.
In the case of my phone, the WiMAX/4G radio is still that 65 nm Sequans, so it's still a hog. (My battery life brags are without 4G, rarely have access to it.)
Without a proper teardown on the Rezound (the only one I've seen still had the RF shielding over the main components, so no way to get part numbers) or a schematic, no way to tell what the LTE or other radios are.
And speaking of RF - an SoC is enough of a nightmare to manage for its own RF with various multi-speed buses - so imagine how much worse that would be if you added the radios into that same chip.
The OMAP4 in Nexus is really something at managing the internal clock speeds to maintain data integrity - can't praise that enough.
The S3 was originally marked as the 8260/8660 where the first had only the GSM modem/controller and the second had that plus the CDMA one. People constantly kept reading that as radios and then causing a negative perception that someone was holding out on them for world-phone capabilities. I'm not 100% sure, but I think that's why they re-named it to the S3 and then took down the sub-model explanations from their public site (last I checked).
And a little PS on anything S3 or Snapdragon - it's not really A8 based (I used to make that same mistake). Snapdragon is to Cortex as AMD is to Intel - they can run the same commands, but just as an AMD is not a version of an Intel, so a Snapdragon is not a version of an A8 Cortex.

If anyone cares, here's a pretty good teardown of the RAZR (not as good as others they've done, but pretty good) -

I was very surprised to find that the full memory package was not a single MCP by Samsung, but rather that plus a Toshiba chip - so I may have to eat crow on the idea that the Gnex will use a single MCP for memory. (Well, that - or Samsung kept those to themselves, we'll soon see I think.)
Hope this helps!
Thanks for the awesome wrapup. That's why I called you the expert.
Sorry, I got confused as well and called it the radios, when it's really the modems. But by that same token, I also believe Qualcomm has developed thier own LTE radios, as did Motorola. Not sure about Samsung.
And as you said, the Snapdragon isn't an ARM design. I like the AMD/Intel comparison, because it's very similar. Also nice how they can run each core at different speeds.
