I have a Treo 650 and use espn.com for scores. Scores are (usually) updated slightly faster than DB Premium (which is extremely irritating,given the $550/mo price). Lines are a different story. BetCris is easy to log on, but difficult to get updates if you're on for any length of time. The WWTS wireless seems easier to use, but my account there is not currently funded so I haven't used it in a while.
