Phone users can enter their phone numbers on the Loco4Local Web site and receive a text message with instructions for downloading the client.

A Microsoft spokesman said that the site is designed as a fun marketing site and offers people another way to download the client to their phones. He did not immediately reply to questions about when the site launched and details about the BlackBerry update.
