Giving Iphoneography lessons

All my friends want to have Iphones, but none of them knows how to use them. I mean they know how to answer and other normal stuff but they have no idea what to do with all the application. When I found out that they want to buy them and learn how to use them, I told them I would give them some affordable iPhoneography lessons. All they have to do is to let me know whenever they want to begin.
