Hotfix
Unity iPhone 1.5.1 is a minor update to the feature rich Unity iPhone 1.5.0 and is recommended for all Unity iPhone developers.
Unity iPhone 1.5.1 includes improved XCode support and improved AssetBundle support, but more importantly Native APIs (NSGetEnviron and exc_server functions) have been removed to comply with new Apple requirements.
The main reason for this is to avoid problems with applications breaking when Apple releases new versions of the iPhone OS.
