how to make motorola droid vibrate when I get a text but NOT on silent mode?

I can make it vibrate for texts when it's on silent, but I want it to vibrate even when it's NOT on silent. But I cant figure it out because under the settings, the four options don't seem to fit. For the option "always" vibrate, does that mean when someone calls me it's going to vibrate too? I just want it to vibrate when I get a text, but I want it to use my ringtone when I get a call.
