Ice Cream Sandwich. It's more than a buzzword in the Android community right now - it's what most users are waiting for in one way or another. Some are waiting on the update to roll out to their device, while others are still waiting to find out if their device will even get the update. For HTC Rezound users, however, the wait ends today - as long as they're willing to flash a leaked firmware, that is.
This is a release candidate for the OTA and by no means a final version.
