Recently Apple’s CEO, Steve Jobs addressed the gathering at the WWDC 2010. He revealed that with the launch of iPhone 4, Apple has taken the biggest jump after the original iPhone launch.

The iPhone was launched three years ago and has been very successful since then. Over these years, the fundamental concepts behind the iPhone have stayed the same though, there have been timely alterations in the operating system and improvement of hardware.

The iPhone 4 is a more sophisticated and competent version of the iPhone and appears to be really cool. However, there are some faults with this modern version as there is concern over the new antennas as the call reception is also problematic.

The accessories, which are available with this new version, are same as those available earlier and include a syncing cable, a wall plug and a set of Apple ear buds with a built-in mic. It is available with an AT& T network throughout America.

The back of the phone is no more curved and the plastic has been replaced by glass. The phone is flat and also comparatively thinner than the earlier versions. However, the overall shape remains the same.
