I created my new game with Unity iPhone 1.7 and I have the iPhone SDK 4.1. When I build my game with XCode it shows me a lot of errors because Unity exported my game for iPhone 3.0. My questions are:
Can my game be exported for iOS 4.1 (or iOS 4.0) with Unity iPhone 1.7?
I read that Unity 3 is coming soon. When will it be available? Can my game be exported to iOS with the new Unity?
Just select unknown as sdk version in unity and in xcode then use project - edit active target settings. Set base sdk to 4.1, iOS Deployment target to whatever you want as long as it is 3.0 or higher.
When its done and yes it can, given you own a unity iphone 3 license and ported the game as it is a new major version and has some changes.
