Update: and just like that HTC has pulled the listing for the 3.14.605 update to Ice Cream Sandwich from the support page. Back to waiting.
HTC has posted the official news that ICS is available for the Rezound, but we can't find anyone who has found it yet. Version 3.14.605.10 710RD should be hitting devices shortly according to HTC and will update devices running the stock firmware to Ice Cream Sandwich, and is installed like any other OTA update through the settings menu.
It's worth noting that this is the same build as the last leak, and one that's been kicking around from HTC in RUU form for those who don't want to wait for an OTA. That's where the Rezound forums come into play, where folks live and breathe this sort of thing and can point you in the right direction for any assistance you might need. In any case, we'll update when we hear news that it's pushing out over-the-air.
