Just as it promised a month back, Sony has started to roll out an official Android 4.0 ICS update for its high-end Xperia S smartphone. The upgrade should have already hit your Xperia S OTA (over-the-air), but, depending on your phone’s model and carrier, you might have to wait an additional few days until getting the much-awaited tasty scoop of Ice Cream Sandwich.

The Android 4.0 update comes just days after the low-end Xperia active has been upgraded and two weeks after another entry-level device from Sony, the Xperia Mini Pro, has been officially taken to the next software level. I don’t know about you, but Sony is impressing the bejesus out of me with what looks like the most well-thought and well-planned ICS update strategy around!

That being said, let’s get back to our post’s topic and talk really quick about the improvements, tweaks and modifications brought by the Android 4.0 update to the Xperia S. These include a lock screen with improved functionality, resizable widgets with better personalization, better control of mobile data consumption, but also three new exclusive apps, called “Walkman”, “Album” and “Movies”.

The Xperia S’ new apps will provide you with “a completely new way to experience your media” and, if you’re curious as to what exactly that entails, you should check out this link here for all the details that might be of interest, or the video clip at the end of the post.

Improved performance in browsing, gaming and multimedia are already standard ICS features, so I probably don’t have to tell you about that, while the new UI will be significantly more user-friendly, interactive and functional.

The OTA update weighs in at a pretty standard 200 MB and you should have already received a prompt message alerting you to install the new software package. If you didn’t get any kind of notification, you should check out your network connection or reboot your phone one or two times. If that doesn’t work either, you’re probably still on the “waiting list”, but, hey, you’ve been patient so far, you can give it a couple extra days, can’t you?

If you’re one of the lucky users already prancing around with an ICS-running Xperia S, please get back to us with a short comment letting us know a few things about the update. Is it everything you’ve expected it to be? Are there any bugs or glitches to report? And is the Sony Xperia S a whole new phone right now?
