Jailbreaking an Iphone
An Apple iPhone is a popular multimedia, internet based smartphone sold and marketed by Apple, Inc. An iPhone can function as a video camera (video recording was not a standard feature until the iPhone 3GS was released), a camera phone, a portable media player, and an Internet client with email and web browsing capabilities, can send texts and receive visual voicemail, and has both Wi-Fi and 3G connectivity. The user interface is built around the device's multi-touch screen, including a virtual keyboard rather than a physical one. Third-party as well as Apple applications software is run on the iPhone to increase the functionality. These applications or “apps” are available from the Apple App Store, which launched in mid-2008 and now has over 500,000 "apps" approved by Apple. These apps have diverse functions, including games, reference, GPS navigation, social networking, security, and advertising for television shows, films, and celebrities. Because of the popularity of the apps and the iPhones capabilities over 37 million iPhones were sold in the first quarter of 2012. However only apps available from the app store can be used on the iPhone. Critics have said because of these restrictions the iPhone is restricted of some of its basic abilities that other smartphones offer standard. Some of these abilities are, but limited to recording video, custom ringtones, photo zoom and the ability to change the look and feel (including icons). To circumvent the restrictions people often turn to “jailbreaking” the iPhone. Jailbreaking a hack that opens up the phone's firmware to allow the installation of third-party applications. Firmware is code that contains the operating instructions for hardware, such as how an iPhone should function, what features are enabled and any security patches that are needed. Jailbreaking the iPhone bypasses these limitations
