I discovered a new SMS service by 411SMS There's only one drawback though, instead of sending text request to a shortcode, you send the request to a phone number. That could be a problem when it comes to recalling what service to use.
Just register once, and save the number in your contacts.
Get business or residential listings, turn-by-turn driving directions, stock quotes, GPS coordinates, Wi-Fi hotspots, price comparison, language translations and definition/spelling checks.
Text "setup411" to 3109043113 or firstname.lastname@example.org to initialize your cellphone and you will receive a text message response on your phone stating that setup is complete.
The GPS application could get legs if they could incorporate search results with it. To find specific coordinates type gps and the address or zipcode.
