The iPhone has impressed a lot of people since its launch. There are a ton of features which set the phone apart from others, such as a multi touch screen, incredible browser and iPod all bundled in to one device. Now, you are able to use the iPhone as a modem to get online by using a program called Tinyproxy. It allows you to surf the net on a MAC laptop at EDGE speeds which are not huge, but still acceptable. Some will wish it had 3G, but EDGE is ok for doing regular browsing on the internet. Also, if I am correct I believe data transfer on an iPhone is free which ultimately allows you to get online with your laptop for free. You can download Tinyproxy from here.
