OUT NOW!!!
Finally, a HTML5-version of FTP's Rush Poker has arrived for all iOS devices (iPhone, iPad, iPod Touch; latest iOS version only, I believe):

It works rather well for being only a beta version. All Rush Poker tables are supported (Hold'em, Omaha, real money & play money).
The table graphics are almost identical to the desktop version of FTP. The only thing missing is the "Quick Fold" button and you can only play on one table at a time.
