Reeder for iPhone lets you read your Google Reader feeds in style
Reeder [iTunes Link] has all the relevant sharing options I've craved in one place - and best of all is stylish as hell. There's plenty of applications with custom user interfaces on the iPhone - some more successful than others - but Reeder balances the familiar with custom elements, and as a result the interface looks great when browsing (and reading) content.
If I had any complaints about Reeder, it's that the application lacks the ability to view your friends' shared items within the application, but given the sheer style and speed of the application it's a small oversight. If you're looking to pick up a copy of Reeder, the developer has dropped the price to $0.99 until version 1.1 ships - and available now on the App Store.
