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.

Thanks to a loyal tipster, we have in our possession the ICS update for the HTC Rezound. As always, since we have it, you have it. Without further ado, here is the download and installation instructions:

Download (MD5: 58b0f42defc689650ddd5128f195dc7d)

The first three mirrors are completely stock builds and will break root. Grab the pre-rooted version if you want to keep root.

Installation instructions for the stock build

This will not work if you used the HTC Bootloader unlock tool. Your device must be fully stock with a locked bootloader.
  • After downloading the file, rename it to "PH98IMG.zip" (no quotes)
  • Place the renamed file onto the root of the SD Card
  • Power down your device
  • Reboot into the bootloader by holding VOL DOWN + Power
  • The flashing process should begin automatically

Let the device reboot, and you're finished. Congrats, you're now running Android 4.0!
