Newbie: How do I test/run the Roll-a-Ball iPhone sample from the Asset store?

I’m a full time c# developer wanting to dip my feet into the iOS world with Unity. I’ve downloaded the Roll-a-ball sample project, and want to see it run. I dont yet have an XCode developer account.
I’ve tried pressing the [play] > button which worked with AngryBots, but nothing happens.

on your iphone appstore look up unity remote then run the app at the same time as the game it will appear on unity remote and you can play it from there
