I've seen a number of neat iPhone apps recently that I'd like to use. In particular, there are a number of neat musical apps (metronome, tuner, etc.) that seem highly rated, and have no real Mac equivalent. I don't have a recent iPod/iPhone/iPad (I don't need portability or a phone and it seems silly to pay hundreds of dollars to run $15 worth of apps), but I do have an Intel (C2D) Mac.

Can the iPhone dev simulator, or any other emulator, download and run iPhone App Store apps?
