Since users of the Apple smartphones can only install software that is available through the app store and approved by the company, the 'jailbreaking' of the iPhones is what is required to install as well as run third-party apps which are not available from the iTunes app store.

Even though thousands of apps available from the iTunes app store add to the functionality of iPhone, the Apple handset users are at a disadvantage as compared to their counterparts who use handsets running the Google Android open-source platform that allows the download of apps from third-party stores.

As such, most iPhone owners are often tempted by the 'jailbreaking' option - which means installing a program that circumvents restrictions in the default software, thereby allowing iPhone users to can run third-party apps.

The process of 'jailbreaking' an iPhone running iOS 4.3.3, first and foremost, includes the opening of the Safari web browser from the Home screen, and a visit to JailbreakMe website. The next step is to press the 'Free' button from the page displayed, and select 'Install.'

After that, the 'jailbreak' button has to be pressed, so as to facilitate the installation of the Cydia app, which can then be selected from the Home screen --- marking the completion of the 'jailbreaking' process. The users can thereafter browse and install any third-party apps they want.

However, it is worth remembering that 'jailbreaking' voids the warranty on the iPhone, and there's no guarantee that the apps which will be downloaded will be free from malware!
