Yesterday I noticed a small bug in the way the phone handles the set vibrate mode in the sound menu. If I set the mode to only in silent, and then change the phone into silent mode using the power control widget, it will change the vibrate mode to never. It also changes it to other modes in different volume settings. As far as I can tell only the power control widget does this, the lock screen slider leaves the vibrate mode intact. Can anyone else replicate this?
