MobileWhack points out that you can now use Google vis SMS.

You can use Google via SMS now, thanks to Google SMS. Use Google to get listings or query things for you in a variety of ways: Simply sending “pizza 02906” to 46645 will get you the pizza joints in my neighborhood. And yes, 46645 is GOOGL. Cooler still are the tipsheets and Froogle price lookups all available via SMS. I think Google just became the killer app for mobile phones.
