Apple has rolled out two minor iOS updates, the first is for the second generation Apple TV and the second for the iPhone 4S. For Apple TV 2, the new build (9A406a) updates system software to 4.4.4, but it’s unclear exactly what the changes are, indicating this is likely a bug fix update. For iPhone 4S, it’s simply a new build (9A406) of iOS 5.0.1, and also doesn’t appear to offer any significant changes.

You can get the updates directly through either devices software update, although the iPhone 4S update doesn’t appear unless you haven’t updated to 5.0.1 yet anyway, indicating it’s not a crucial update for all users. If you prefer to use IPSW manually, these are the direct download links from Apple:

There is some speculation that the iPhone 4S update may relate to international releases of the device, which is occurring tomorrow in a variety of new countries, including Russia, Brazil, Chile, Thailand, Malaysia, Taiwan, Philippines, South Africa, Saudi Arabia, Turkey, Israel, and Vietnam.
