The T-Mobile Dash running Windows Mobile 6 has one really annoying bug: Once you set the phone to vibrate profile, event notifications always vibrate even if the profile is set back to normal. However, there is a workaround if you use a Bluetooth speaker or headset. The Dash comes with Voice Command in firmware. If you set it to send voice notifications to the Bluetooth device, the darn Dash will still vibrate for event notifications, but it will provide a text-to-speech notification via the Bluetooth device.
