Looking for reverse phone lookup info

Several months back someone posted a way by which you could text a phone number to a service that for a small fee would respond via text with the phone owner's name. Can anyone link me to that thread? Thanks. I've tried searching to no avail.

 

Thanks, but I now remember how I did it. Text the phone number you're interested in to LOOKUP (566587). You get a text back, and if the number was found and you agree to a $1.99 fee, they'll text back the name (but ONLY the name.)
