Well its free, so I gave it a shot, and i am impressed. It was extremely fast over wi-fi. Edge was slower of course but still managable. All the features work great but I have not tried to purchase tickets through the program.
There is a known bug for this app according to the author who will fix it on the next update. Apparently sometimes when you put your zipcode in, the keyboard does not hide itself. It hasnt happened to me yet though.
