Paul,
If you live in the state of Nevada you can set up a "phone account" with some of the sportsbooks, but if you live outside the state, no luck. I assume you don't live in Nevada! Online and phoning across state lines is a no-no! The legality (of bets originating within the U.S.) of the offshore books is still being debated. Some of the offshore books have a great reputation, but even one of the most highly regarded books folded after the last SuperBowl and the money just disappeared! Understand there were some pretty heavy players that got stung with 6-7 figure loses. I would avoid them all togehter.

Just jump on a plane and go to Vegas! It's all legal, the sportsbooks aren't going to fold, you get your money 10 minutes after the game's over and you can stop by the Palms and harass Trimble, all in the same trip!
