I recently downloaded the new Audible iPhone app and let me tell you it is sweet!
2. Able to playback audiobooks in iPod application
3. Able to download audiobooks you’ve purchased over WIFI
4. Able to bookmark/notate your favorite spots in an audiobook
5. Hasn’t forgotten my position in an audiobook yet like the iPhone’s iPod app does frequently.
6. Special swipe and tap interface for fullscreen control without looking at the app.
1. Not able to change playback speed (a big deal to me)
2. Not able to stream audio content that you’ve purchased (you have to download and most books are too big fo 3G)
