Load up Treasure Isle
and look to the bottom of your game today and you'll find a survey promising you 2 free Island Cash. All you have to do is pick one of three choices to this simple question: "Which Windows Phone 7 feature are you most excited to have in your pocket?" After that, you'll be led to a window asking you to join the phone's Facebook page, but you DON'T have to. Answering that question is the only action required.
Before you go running off for your chance at free premium cash, here's a heads-up! Players who have already completed Windows Phone 7 survey on June 4th

might be disqualified from getting the cash because they've already done this survey. But hey, it can't hurt to try.
