I personally would go with mr2.
I am running das bamf sense 3 rc4.9
put rom on root of sdcard
install clockworkmod via rom manager (get rom manager from market)
then go into recovery. Wipe data, wipe cache, wipe dalvick.
Then select install a .zip from system or sdcard (something like that)
press up and it iwll take you to your .zips
choose the rom and it should install. Once installed you will be taken back to recovery mode.
just choose to boot normally into your phone.
once you're in put the radio should be named PG05img.zip into root of sdcard)
Then after all that is done, your rom most likely will have load into bootloader when holding the power button. For example i hold my power button > choose restart > choose bootloader.
So once you've loaded into bootloader, just wait and it will ask you to update your radio, press the volume up button and the radio will auto update.
Once this is done, delete pg05img from root and be on your merry way.
