Been using this for a while, thought I would let everyone else know about it. I have Google (46645) in my contact list which makes me look like a huge nerd when people are browsing through my phone.
You can do some cool shit with this tho. I usually use it to find out the times a movie is playing, and all I have to do is text message google with this: <zipcode> <name of movie>. Getting driving directions is pretty cool too. Check out the link above for other cool shit you can do.
