2. if this can be accomplished VIA RadioComm Has anyone dabbled in the MPQ Firmware Specificly for US carriers?

You need to be on stock ics firmware for the NV edit to succeed and stick.
Use Android 4.0.4 Blur_Version.77.8.14.XT897.Sprint.en.US - http://sbf.droid-developers.org/phone.php?device=3
If you're downgrading from jellybean, you have to remove the line with flash gpt_main0.bin from the xml file, otherwise the flashing via rsdlite will fail.
<step operation="flash" partition="partition" filename="gpt_main0.bin" MD5="6C05E70F1DCC59AD92B0BBEC4E6100ED" />
The firmware thread is here: http://forum.xda-developers.com/show....php?t=2095536
Then you can follow this (RadioComm):
or this (CDMA WS) guide:
After it's done, you should flash the stock Android 4.1.2 via rsdlite, then install CM10.2 (or any other custom ROM) again.
