TB, I have no issues with viewing the rx on my iphone. The Greek and Olympic work really well also. Matchbook seems to be a pain in the ace on it though. Takes much longer, definitely not instant. I'd check the app store and online forums to see if there's a solution to the problem. Not sure if it makes any difference but are you on the 3g network or using wi-fi when you're attempting to go to Bookmaker?
Buddy of mine got one the first day it came off. He showed it to me and the first thing I said, "hey, let me see if I can pull up my sportsbooks and place some wagers." I did. Out the door 1 minute later to get one..lol.
