This is annoying... when I turn down the volume, or use a widget to set the phone in vibrate mode, none of my notifications will vibrate. I'm using the built-in Gmail application for my Gmail account, and HandCent for SMS. Neither will make the phone vibe when I get an email or SMS. I have set HandCent to vibrate notification when the phone is set to vibrate mode, but no vibes. I've set it to vibrate on EVERY message, and it still doesn't vibrate. Done the same with the Gmail app, but the only choice in its settings are to vibrate on every notification. I just want the stinking phone to vibrate on notifications when I have the stinking thing set to vibrate!
