For future reference, the path of the iOS simulator in the iOS 5.1 SDK:
/Applications/Xcode.app/Contents//Developer/Platforms/
iPhoneSimulator.platform/Developer/Applications/iPhone\ Simulator.app
You’ll need this if you want to test for retina iPad. It’s now showing my default since iOS 5.1 since it’s now part of the Xcode bundle. To navigate to it in Finder you would right click on XCode and choose the “View package contents” option. Thanks Jan and Werner.
