iphonefeeds.net is great way to find relevant RSS feeds specifically for iPhone users.

RSS feeds work particularly well on the iPhone. As the leading mobile device, packed with applications, many iPhone feeds interact with the main Apps pre-installed on the iPhone:

- Safari Browser
- iTunes App Store
- iTunes Wireless Store
- QuickTime.

Examples include a news article that automatically opens the Safari browser, or a listing about the latest Free iPhone Game that opens the iTunes App store on your iPhone. Really clever stuff!
