Hi HN,
We recently shipped SoundGecko v2 for iPhone with a brand new feature set.
If you visit http://soundgecko.com/hackernews you can get Hacker News & Growth Hacking artucles on your iPhone.
Android, Windows Phone, BlackBerry and desktop users can listen too using the web stations view (mobile friendly) - updates to those apps are on their way.
Cheers, - Andrew
