HTC seems to be hard at work on getting Ice Cream Sandwich Android 4.0 to their devices, evidenced by the Over the Air (OTA) firmware that have been leaked for different HTC devices, indicating that HTC is indeed working to get ICS out to the masses as soon as possible. The latest device to see Ice Cream Sandwich leaked through OTA channels is the HTC Rezound, with the new 3.11.605.2 firmware. It still only comes with Sense 3.6 instead of Sense 4.0, but the final version will (hopefully) feature Sense 4.0 instead of 3.6.

The firmware is a release candidate for the OTA update, so it’s definitely not a final version, so expect bugs scattered here and there. Here’s a look at the features of the firmware:

  • 1. Android OS 4.0.3 (Ice Cream Sandwich)
  • 2.  CMAS support added
  • 3. IPv6 over eHRPD supported
  • 4. UI updated to Sense 3.6
  • 5. Caller Name ID app added
  • 6. VMM/BUA plus updated
  • 7. New storage UI (under settings menu)
