Apple has updated the software for Apple TV, without fanfare, to version 2.1.

The updates include security improvements, support for using the iPhone or iPod touch as a remote, and support for Mobile Me content.

What would really excite us would be if Apple opened up Apple TV to developers, like it has with the iPhone, or if it supported Hulu – but it looks like that may have to wait for version 3 of the software.

TUAW has a gallery of images for the update.
