Android 4.0 (aka Ice Cream Sandwich) has been available for a little while now, but many carriers and manufacturers are still working hard to roll out official updates. Today, Samsung began rolling out an Android 4.0 update to its unlocked Galaxy S II devices in America. While users of carrier-branded Galaxy S II devices will continue to wait for an update, there are plenty of carriers and manufacturers that are working on updates of their own.

According to details shared with Droid Life, Verizon Wireless is getting ready to release an Android 4.0 update for the Motorola Xoom (3G/4G) tablet as well as the HTC Rezound smartphone. Both of these devices are expected to get Ice Cream Sandwich in the next two to three weeks.

The Motorola Xoom tablet is expected to receive the update first. Rumored dates currently suggest the update will begin rolling out on April 23. This update will be for the 3G/4G version of the Xoom. The Wi-Fi only version of the Xoom tablet began receiving updates to Ice Cream Sandwich in January.

Verizon Wireless is expected to begin rolling out an Ice Cream Sandwich update for the HTC Rezound on May 9. Various sites claimed the Droid Razr and Droid Razr Maxx were scheduled to receive an update to Ice Cream Sandwich on April 4, but that didn't pan out. It appears Motorola and Verizon are having some issues with the Android 4.0 update. The companies have not said when the official Ice Cream Sandwich update for Droid Razr and Droid Razr Maxx will be made available.
