iPhone which is a combination of an iPod, PC, digital camera and a mobile phone is one of Apple’s greatest creations. This device does not require a stylus or a hardware keyboard to navigate. It is a multi touch interface that brings the world to your finger tip. One has to just navigate through multiple taps and drags to reach the desired destination. iPhone is called the mobile version of OS X operating system which is also created by Apple. Similar to the iPod, the synchronization of data with the user's personal computer can take place in iPhone. All you need here is iTunes and Apple's proprietary USB port. The best part is iPhones are compatible with Microsoft's Windows operating systems.
