Verizon is rolling out yet an OTA update to the HTC Rezound as of this morning, this one claiming to add "HTC Device Enhancement" (only one enhancement, obviously), so we're not quite sure what's inside. The new version number is 3.14.605.13 710RD, and you can probably expect it to begin rolling out some time this week.
The Incredible 2 is also getting some OTA love, with the some sort of cryptic changelog. Given that we saw a totally unexpected security update to the now-ancient EVO 4G last week, it seems possible these "enhancement" may be security-related as well.
