where I work we've had to put some gifted people into the process of automating analysis of websites to see if they're small-screen friendly (iphone, smartphone etc), and even then it's hit and miss and needs live humans to review the results. there are far too many organisations which think a simple custom CSS style, or a custom skin for a forum, wiki etc, is sufficient to make it mobile friendly. however, it is getting better. I've seen the stats.
They're maemo and MeeGo... "Meamo!" sounds like what Zorro would say to catherine zeta jones... after she slaps him for looking at her dirtily...
