The update brings the 'Bolt up to Android 4.0.4 and HTC Sense 3.6, and weighs in at a little under 400MB. According to reports from the Android Central forums and elsewhere it's available now for download, so go get it! Head to Settings > About phone > Software update to see if your update is ready.
