The iPhone took the entire mobile phone market by a storm with its launch. iPhone is not just a next generation mobile but it is device which provides high end facilities like high-speed internet access to its users. It is a product from Apple (formerly Apple Inc.), which has lined up many other advanced technology based electronic devices (how can we forget the classy iPod). No surprises, iphone website development and iphone application development, both are the craze of today.
Apple provides an outstanding Software Development Kit (SDK) to enable users and developers to expand the iPhone to higher levels. It is a great platform for users who love to use various other applications than iPhone originally offers. There are many firms that develop customized applications for iPhone. Generally, a company or an individual seeks services of such development firms to outsource iPhone application development.

Now, the iPhone applications can be divided into two categories:

native applications and
web applications.

The iPhone application developer utilizes the tools and technologies in SDK to develop native applications. It is much like developing applications for MAC OS X. Moreover, an iPhone simulator facilitates the testing and debugging of the applications before they are ready to be used.
For the web applications, the availability of standard web application development tools comes as a boon. iPhone uses finger impressions as inputs rather than a mouse. This raises the need for iPhone specific web pages and it is known as iPhone website development.

The other challenges that an iPhone application developer faces are the variations in display size of web pages, namely wide-screen and portrait screen. All these make the iPhone website development distinct from the simple website development.

With the launch of iPhone, Apple has opened up a newer market for development of customized applications for iPhone. It is because iPhone has a wide and an increasing customer base. Hence, the professional development firms have found a new segment since the need to outsource iPhone application development projects is reaching newer heights.
