HTC is focusing more and more on updating its existing Android smartphones to Ice Cream Sandwich. Earlier this week, the manufacturer rolled out an Android 4.0 update for Sprint EVO 3D and EVO Design 4G. The next device in the queue is the renowned HTC Rezound, offered exclusively by Verizon Wireless in the U.S.

On Monday, Verizon posted two update manual documents regarding the Android 4.0 update for HTC Rezound on its website. The update is officially listed as "Coming Soon". However, HTC Rezound owners have been reporting receiving notifications for the update since Wednesday evening.

The update is OTA (over-the-air). Needless to say, downloading the 299MB package over Wi-Fi is recommended. As always, the update is rolling out in phases and it may take few days to reach all Rezounds. Once the update is available, users will receive notification on their screen regarding the update.

According to Verizon Wireless, the update brings the following enhancements, apart from native ICS features.

Application and Widgets

•  V Cast Media Manager has been updated to Backup Assistant Plus with an enhanced user experience.
•  Time zone issues have been resolved and proper Timezone will display within the Clock Widget.

Device Features

•  Device is enabled with the Wireless Alerting System.
•  Cisco AnyConnect support has been added to improve VPN functionality.
•  Improved data connectivity for a better user experience.
•  Improved device stability minimizes the number of resets.
•  Improvements to Mobile Hotspot connectivity.

E-mail, Messaging & Web

•  Improvements to default mail application now displays all Yahoo! Mail contents properly.

HTC Rezound debuted in November last year on the same day Google first released the Android 4.0 ICS source code. HTC Rezound is a rare device to outmatch iPhone 4S' pixel density. It is also one of the first HTC's devices to feature Dr. Dre's Beats Audio enhancement.

HTC took nine months to release the ICS update for the device. After Android 4.0, the next trend in the update league is Android 4.1 Jelly Bean. The device fulfills every requirement to run Jelly Bean. However, do not expect the Android 4.1 update anytime soon.
