Thanks for this !!!!

I would like to add that 1.53.00.02.15_23.17w.05.13U Manga v3 radio may also be part of added support for CMAS or Commercial Mobile Alert System. CMAS was added to the operator package of the Verizon Mango v3 driver:

From: 438ABF0C-B691-4259-A742-1F224FA3B5BA.rgu

[HKEY_LOCAL_MACHINE\Software\Microsoft\ShortMsg\Settings]
"CmasOperatorEnabled"=dword:1
[HKEY_CURRENT_USER\Software\Microsoft\ShortMsg\Settings]
"CMASAlertOption"=dword:1
[HKEY_CURRENT_USER\Software\Microsoft\SMS\Broadcast]
"TestPort"=dword:4370

These are the new registry settings, and they did not exist before.
1.53.00.02.15_23.17w.05.13U might be required for this to work, but I have no idea how to tell. It's an interesting feature so you'll need to check your registry to see if it is enabled. I know DFT Freedom doesn't have it (yet), I'm not sure about ansar's roms since I haven't tried it yet.

I updated my wife's park_w to Tango via Zune (bone stock phone) and she has a even newer radio on it, in-case you want to find it and add it to the list

Still no official stand alone rom from Football. Unless he or someone else releases one, I have no easy way to extract radios.

I looked into finding the radio files in the rom update.cab files... but its a bit dangerous even if I could find it. :/
