I tried as this article http://www.adobe.com/devnet/dreamweaver/articles/phonegap-mobile-app-p t1.html
And I success to build. When I clicked 'build and emulate', saw the succeed message window.
But iPhone Simulator didn't excute and built app didn't setup.
Please answer me about this problem.
I have the same problem, at first I got error messages, that it was unsuccessfull to build app, but I fixed it with the help of this post: http://forums.adobe.com/message/4002753#4002753#4002753
now my app was build successfully, but the emulator doesn't appear
xcode is in stalled and the settings are propperly pointed in the right direction (I believe)
any help is appreciated
