Honestly, I think a mobile version of the site would be easier than writing an actual App.
Especially for the articles and such, that would not take terribly long at all. Plus the main site blows ass for mobile phones as is. I mean really, loading all of the FA stuff, along with huge ass images AND a flash video, that's going to buttfuck even the most current phones out there.
Another problem with writing an app would be that the Mods/Tech support people would have to familiarize themselves with the iPhone SDK, which takes time (how much i do not know). And even if you do that, how many people have iPhones that visit the site? Personally, i own an Android based phone, so it would be useless to me.
Mobile version > Android/iPhone app.
