Buying tickets using the “choose seats” function on iPad/iPhone

When buying away tickets on the online box office, I really want to use the “choose seats” option on my iPad or iPhone. Because that function requires flash (which Apple obviously doesn’t support), I find myself either settling for using “quick seats” or waiting until I can use a pc, which I don’t always have regular access to. I’ve tried downloading a couple of other browsers that claim to support flash, but the ticket website is still having none of it.

Please, does anyone know of a browser app or some other thing that I can do or download that will make the choose seats option work?

Thanks
