If you upgraded to the iPhone SDK 2.1 and found that the default SDK setting in the Project window is showing “Unknown SDK”, you can easily fix that by going to Menu->Project->Edit Project Settings. In the General tab of the Project Info Panel, set the Base SDK for All Configuration setting to “Simulator - iPhone OS 2.1″ or “Device iPhone OS 2.1″.
