I have recently noticed in my Xcode 3.1.3 that I can completely revise some code (i.e change the icon pic or even a whole background pic) or add/change some methods that work beautifully in the simulator but when I do a device build I get the old code, sometimes several revisions back. Even pics that are deleted out of of the project (references and moved to trash). Just now trying to change the app icon. First swapped out similar named file. Then deleted it. Then renamed it something else and I still get the OLD app icon. Help driving me nuts!
