Unity iphpne example projects black screen

Hi, ive downloaded the unity iphone example projects (star trooper, roll a ball, tunnel runner, iphone match)

When i load them in unity iphone 1.7 , it states that it needs to upgrade them. once they have been upgraded and loads there are no objects in the hierarchy windows and the game view has a black screen and i get script errors (example - star trooper- Assets/_Scripts/PlayerControls.js(31,24): BCE0018: The name ‘Touch’ does not denote a valid type)

Whats going on?

Thanks!

Some of the iPhone API has changed since 1.7 (mainly to remove the “iPhone” part from the function/class names). Code written for 3.0 would use the Touch class rather than iPhoneTouch, for example. You will need to modify the code to use the old class names and possibly make other changes to get the project to work under 1.7.

Thanks!
