I just bought the Optimus Pro C660 and it will vibrate when I get a call or the alarm clock goes off but it won't vibrate when receiving an SMS. I have gone through all the settings and set it to "Vibrate Always", but it still doesn't work. I heard that you can download apps to make it vibrate - would that help? Are there any other solutions for this?
Go to Messaging. Select setting. Go to notification settings. There you have an option to switch on vibration for Notifications.
If you're willing to go with a 3rd party app, I'd recommend Handcent SMS. It goes a step further by allowing you to assign specific vibration patterns to different contacts.
