Civ on the iPhone sucked away two weeks of my life. It's a great port and reminds me more of Civ2 than the newer ones. I'd recommend the download on your winter break ;)

In my opinion it's not terribly good - the are you can see it far too small to move units in an efficient way, now I have to scroll around all the time. Or have I missed how to zoom out?

[edit: I just started the game, and sure enough it's possible to zoom. slaps forehead for not trying it before]

Don't beat yourself too much about that. I had the exact same problem. Took me a few days to realize that zooming was even possible.
