Question

I have created a Cordova 2.1.0 app, It ran fine for the first 2-3 times. But now when I am trying to run it through terminal it is giving me the following error.I didn't change anything.

Ankurs-Mac-mini:~ ankur$ /Users/ankur/Desktop/CordovaSMS/cordova/emulate 
Ankurs-Mac-mini:~ ankur$ 2012-10-17 16:11:08.695 ios-sim[7032:507] stderrPath:

Solved the problem

Deleting contents of ~/Library/Application Support/iPhone Simulator and re-run the project solved this problem. or you can simply reset content and setting of the simulator.
