The radio has been extracted from the new OTA update and posted on XDA and Rootzwiki. XDA: [RADIO] HTC Incredible 2 Radios [PG32IMG.zip] (Updated: 20 Sept 2011) - xda-developers RW: [RADIO] HTC Incredible 2 Radios [PG32IMG.zip] (Updated: 20 Sept 2011) (I didn't do the work, just getting the information out there.)
I pulled this from the unsigned dump posted by jcase last night and have been running for about 13 hours now. I am seeing a significant improvement. (I am running MIUI, but that doesn't really matter that much for the radio.) Previously with 0622, I was consistently 10-20dbm lower than my OG Droid sitting right next to it. Now they are almost equal. I have never seen my dinc2 get better than -80 and I am currently at -73dbm in the same location where before the flash I was at usually -85 to -100dbm.
Seems like a keeper.
One thing that these install threads do not share is to delete the file from the card after you are done or rename it to something other than PG32IMG.zip or every time you try to boot to recovery (or the bootloader) it will try to install the radio again. If the file has become corrupted and you install it again, big problems can result.
