So in addition to the other projects they’ve got going on for the iPhone, id Software (specifically John Carmack) has been working on real ports of Doom and Wolfenstein 3D for the iPhone. Obviously you’ve got more impressive games available, but who can resist taking up a couple megs of space with one of the original first person shooters?

In an extremely long description of how he went about making and tweaking the game, Carmack reveals his undying love for his old-school work and also reveals that he’s working on Doom. Is this the killer app for the iPhone — finally?

You can download it straight up, or get it from the App Store. Don’t worry, I’ll let you know when Doom drops.
