How to get my LG verizon vortex to vibrate when turned to silence?

As right now the phone is set to vibrate "always". It does mot vibrate when I recieve texts, It does vibrate when called and when volume is up it signals sound when texts come in. So how do I get my LG verizon vortex to vibrate when turned to silence?|||I have an LG, and on my phone if its on "SILENT" it wont vibrate, but theres another setting, called vibrate or something like that, and then it vibrates but is silent if you know what i mean|||From Home Screen Go To Menu%26gt;Settings%26gt;Sound %26amp; Display%26gt; Silent Mode Must Be Checked, right below silent mode should say vibrate, press it,and choose always or only in silent mode
