Because the Simulator 3.2 and 4.0 in the SDK 4 do NOT actually work for iPhone simulation (which always comes out iPad and not responding at all), I ended up with 2 SDK installations, using SDK 3.1.3/Simulator 3.1 for simulation, and SDK 4 for building onto the iPhone with OS 4. (More details here.) I tried to use the old Simulator 3.1 ...
