Honestly, I think a mobile version of the site would be easier than writing an actual App.
Nerd Alert: 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.
Short version Mobile version > Android/iPhone app.
