iPhone is a best example of engineering and design capabilities but still there are some issues that need attention. Like the Safari mobile browser which is the best mobile browser does not work unless the user is close to a WiFi hotspot. With Safari every click is a connection over the cellular Internet. Another issue is that iPhones use slower EDGE network of AT&T and not the 3G network. This leads to a slow speed. And affects the quick click widgets which is an important part of the iPhone experience. Once Apple sorts these issues iPhone will be flawless. But still it’s a must buy.
