Wifi play locks up!!!

I play with an iPhone 3 gs and my wife plays with an itouch. We can only finish about 1 of every 3 games we attempt. Its really annoying when Im spanking her butt and it locks up close to the finish. That and the fact that you cant "unselect" a domino you change your mind on or miss select. Fix those and its a five star game...
