As you may probably know mobile design is getting more and more popular, particularly the iPhone design. Almost every popular website or web app offers a mobile version now. In this post, I've collected a list of 38 nicely designed sites (ranging from personal, blog, portoflio, editoral, web app, etc.) that are optimized for iPhone. I hope this list will come in handy when you need to design a mobile site for yourself or clients. Now have you iPhone ready and enjoy the list.
