iPhones and application developers:

The simple and easy to use applications from Apple have contributed immensely to the phenomenal popularity of iPhones. The best apple apps for iPhone are developed by freelancers who develop applications that are extremely useful and user-friendly and thus, have reaped handsome dividends. These applications are available only through apple stores. The arrangement with developers is that 70% of the sale proceeds of the application developed by developer will go to the developer and the rest 30% will go to Apple.

Applications development:
Application development is the process by way of which development of new and innovative applications is encouraged for PDAs, EDAs and other handheld devices. The development of apple applications requires a simple approach for the appto be very popular and to be sold easily. It should be easy to use and must be fun to work with. In order to develop an application for iPhone, the coders will have to use Objective C, which in turn is based on the C programming language. The iphone OS comes with a debugger integrated in Xcode IDE to remove any bugs. Right now, it is the only platform to develop iPhone applications. It is available on Mac OS X 10.5. All the applications developed for iPhone must be approved by Apple before it can be launched via Apple app store. The best apple apps for iPhone can be found in the app stores and can be easily downloaded. The platform to develop applications is run by a development environment. In this case this development environment is iPhone OS which uses ARM architecture. These are binary codes which are executed in native machine format.

The iPhone OS:
The iPhone OS offers free SDKs and integrated development environments. Tools for developing application are free for an Intel-based MAC. However, installing a device requires a fee so that a developer signing key can be provided to developer. Simulator testing is free and requires no fee. SDK or the Software Development Kit for iPhone OS was launched at the iPhone Software Roadmap event on March 6, 2008. It allows developers (running Mac OS X 10.5.4 or higher on an Intel Mac) to develop their own applications using Xcode, compatible with iPhone. The final version was released with the iPhone 3G. This Roadmap event and the large distribution program for 3rd-party developers came to be known as the iPhone Developer Program.
