Simulator won't recognise difference in apps??

[elfarez]

Ok, I have only just got into app developing and as my first project i have made a utility/entertainment app (there is a lite version and a full version). However, to make my lite version I cut corners in that i just duplicated the full version, changed the name, the icon, removed some content and added iAds. However when i run the lite version in the simulator it overwrites the full version app and vice versa, does anyone know the solution to this problem?

They need to have different bundle identifiers, its one of the entries in your Info.plist file
