We wish all devs were as forthcoming as id's John Carmack. His update on the status of the iPhone version of Doom (or Doom Classic, as he's calling it) is exhaustive, but it's also rich with information and insight into porting an old-school classic onto new tech ... and doing it well.

We've dug up a few nuggets for you, like the fact that Carmack says he should be able to submit the game to the App Store by next month and that the game will use the original Doom sprites, but you should really take a few minutes to read the whole thing, it's really interesting stuff.
