The iPhone 4 model, which is manufactured by Apple, Inc., can be jailbroken by using paid-for software, such as iJailbreak Pro. Jailbreaking pertains to the method of removing hardware and firmware restrictions on the iOS operating system. It also disables limitations placed by mobile carriers.
A jailbroken iPhone 4 provides its user full control of the device. Using iJailbreak Pro, the process is done using three simple steps: purchasing the product, installing the program and then following the instructions to successfully jailbreak the smartphone. Once the iPhone 4 is jailbroken, access to hidden features and full customization of the device is possible. The launch time of applications is also enhanced with the use of shortcut gestures.
