The iPhone created quite a splash when it was given to the public. You may wonder why the public, who is more technologically advanced than in previous years, was so swayed by this phone. The reason is simple. The iPhone is full of never-before-seen technology and delivers it all in a highly effective trim little package. It is the combination of two very popular devices, the iPod and the mobile phone.

This 'crossbreed' invention operates on quad-band and supports EDGE technology for enhanced GSM functionality and standards. The Time magazine named the iPhone as its 'Invention of the Year 2007.'

The features available on the iPhone include the ordinary caller ID, call merging, conferencing, caller holding and various cellular network integration functionalities. Besides these, its unique features include the noteworthy visual voicemail feature. The convenient functionality lets you access your voicemail messages individually and directly, instead of listening to all the messages serially.

The internet browsing capability is another important feature in the iPhone. An HTML email client provides easy and quick access and you can sync bookmarks between your iPhone and computer easily. Safari, the best mobile web browser, is what's used in the iPhone.

The iPhone is especially helpful when you need to find alternative routes during traffic jams. The Google Maps feature in it can provide various satellite images and maps of the local area for you to decide on a different road to take. Traffic information is directly available via this feature.

Apart from these excellent features helping to make life more convenient, the iPhone has a touch-screen measuring 3.5 inches in width. The large screen permits more workspace and provides better video quality.

The iPhone display has a tri-sensory responder system: the first unit acts as a shut off device when the iPhone is too close to the user's face. This is to prevent accidental entries from the user's facial contours. The next sensory unit is the ambient light sensor, which adjusts the display brightness according to the environment. The final unit is a 3-axis accelerometre, which can sense the phone's specific angle and change the screen suitably.

The iPhone is the must-have technological gizmo of the new era. WiFi connectivity, downloadable music and movies, bigger screen and the sleek look have contributed much to the iPhone's appeal. Interestingly, with all that great functionality, the iPhone's main use is email checking. Over 77% of iPhone users check their email on it everyday. The next most popular iPhone activities are web browsing and downloading.
