Maybe I'm not looking hard enough but I've yet to come across an app that can send contact info via SMS (not MMS) both in plain text form and as vCards.

Apparently an app called iSMS/weTool could do this, but it doesn't seem to be available anymore.

Even looking through the Apple app store only yields solutions for sending vCards via email, which is less than useful and redundant now that OS 3.0 can do it natively.

Any ideas?
