I found this mobile search engine and thought you might find it useful. 4INFO, provides a FREE sports score update and alerts service via text messaging that requires NO registration and will not SPAM the user.
So, if you want to check the Cavs scores from the office, mall, airplane or wherever you are, simply send CAVS or any team name in a text message to 44636 (4INFO on the keypad)
In a few seconds you will receive a reply text with the current score or previous result and next game information.
