I want to allow users to set the GPS information on the iPhone Simulator via GUI.
But I'm not sure how to archieve this - it seems that this tool called iSimulate does this somehow by installing an own SDK. But I can't figure out how they "override" / "hack" the simulator by that.
Thanks!
The iOS Simulator has full location simulation built in. From the "Debug" menu, you can explore your various location options.

Check out the bottom right entry on this page. I'm under the NDA so I can't say anything except that it has saved me significant gas money. :)

In Xcode 4.2 we can simulate . There is a location symbol on the debug area (while you run the app). There are some predefined locations . Also we can add new GPX files
