iPhone OS 3.1.2 Released Today

Now don't get TOO excited! It's not much of an update. Here's the rundown of what iPhone OS 3.1.2 brings:

iPhone OS 3.1.2 Software Update
This update contains bug fixes and
improvements, including the following:
• Resolves sporadic issue that may
cause iPhone to not
wake from sleep
• Resolves intermittent issue that may
interrupt cellular
network services until restart
• Fixes bug that could
cause occasional crash during
video streaming
Products compatible with
this software update:
• iPhone
• iPhone 3G
• iPhone 3GS

Nothing to get worked up about. But, it is an update and may prevent future performance problems.

There's also an update to the AT&T carrier setting but I don't know what that does so far. Peeps on the internet say it's NOT a tethering update.
