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:
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.
