I've been writing a 2010 MN State Fair guide app for the iPhone entitled Fair on a Stick. It will be a free download once it's available, and you can read more about it at http://faironastick.com
I'd love any feedback on it you might have, and I'd love it even more if you tried it out in a week or so once it's available in the AppStore.
In the interest of keeping this HN-topical, if you like the site template I used, you can check it out at http://jonnotie.nl/templates/iphone/. Also, the site is hosted on Heroku and the template has been converted over to Haml. I plan on making my Railsified app template available on Github in the near future. I'll reply back to this email once it's up.
Cheers,
Aaron
