Installing the RUU is not rooting/unlocking or anything else to make your phone non-stock, the .12 RUU IS
the official ICS update, it is the same as the OTA update just the full ROM and it will wipe all the data from your phone. Yes, you will receive future OTA updates. It can be downloaded from AndroidPolice here: [Exclusive Download] HTC Rezound Ice Cream Sandwich RUU For Final OTA (3.14.605.12)
And MrSmith over at AndroidCentral.com did a nice write up on how to flash it here: [How-To] Flash a leaked RUU - Android Forums at AndroidCentral.com
