HTC has announced today that European HTC Magic users are now eligible for a firmware upgrade that enables the company’s lauded Sense UI.

Shown in the video below, the Sense UI is a full GUI replacement for the stock Android firmware. In addition to replacing all graphics and navigational elements, the Sense UI broadly expands the quantity and quality of the gadgets that can be placed on the desktop. Sense has also received critical acclaim for its contact integration features, which expands the scope of Android’s messaging outlets to include resources like Twitter.

Would-be updaters are advised to back up any important data, as the firmware update completely erases the device. HTC also warns that carrier-specific applications will be destroyed in the process.
