Android fans are eagerly anticipating the release of Google’s upcoming Ice Cream Sandwich operating system, and thanks to this two-minute video, we get a sneak peek at what’s in store — including improvements to the camera app and changes to the user interface.

This is Ice Cream Sandwich — the successor to Gingerbread and Google’s first one-for-all OS — running on the company’s Nexus S smartphone. As you can see, there are a few things that are noticeably different when compared the the OS that we’re rocking today.

There are now four buttons on the bottom of the home screen and a new Google Apps button, which, as you’d expect, is home to all of Google’s official applications. The camera also seems to have been improved, and many of the menus have been tweaked.

It’s possible, of course, that this could be a clever fake created with a custom ROM, but the baseband, kernel and build numbers would suggests it’s legitimate. The tipster, who first sent the video to Engadget, also claims that the device has since been remotely wiped and locked — leaving it unusable.

Based on that video, are you excited about Ice Cream Sandwich?
