Google has taken the wraps off of a beta release of Google SMS, a preliminary mock up of a service offering that extends Google's reach to cell phones and other handheld devices.

Participants can write and send specialized queries to Google's 5-digit U.S. shortcode to find out what they are looking for within a specified zip code. Google SMS returns names, addresses and the phone numbers of local businesses and residences; provides a dictionary lookup, and compares product prices between local retail stores.

While it may not yet be as simple as dialing 4-1-1, users may text 46645 (GOOGL) to participate in the beta program.

At the present time, the service is only available in the United States. The service works with leading wireless providers including AT&T Wireless, Cingular, Nextel, T-Mobile, Verizon, and Sprint PCS. For more information visit the Google SMS Web site.
