Answer 1

I still wish the original problem was solved (ERROR: Simulator not available) but the answer from DaveS helped me get to where I could load it on the simulator.

After building with appc, the correctly built .app file was in myproject/build/iphone/build/Products/Debug-iphonesimulator then I could just drag and drop that file to the simulator (or probably use the command in Dave's answer but didn't try yet) and the app is properly running on my device.
