In today\\'s international of consumerism, one is ne'er adequate for us. race are always desire for more than and much. And when we are people in the era of engineering where multi tasking is the mantra, how can we be rewarded beside any device which can serve solely one meaning. If we pocket the mock-up of seaborne phones, we see that these miniscule inclination have come with a agelong way and nowadays these are not honourable medium of interface but can be utilised as a camera, music players, mini camcorder, diversion devices, web explorer, mini computer and what not. The index is perpetual.
With all passing day, we are acquiring new and developed models of manoeuvrable phones which are powerful of handling multi-tasks at the same time.

First came the photographic camera feature, past auditory communication player, consequently wireless connectivity through Infrared, USB and Bluetooth, past Internet admittance done GPRS, WAP, XHTML and now 3G and WLAN. Isn\\'t that a great achievement? Of course of study it is! That\\'s the muscle of engineering.
