Android Rooting and iOS jailbreaking, these terms might sound analogous to their platforms, however, they are not. This write-up explains differences. You can’t really interchange terms and say jailbreak android and root iOS because they are different processes and provide different levels of access.
Lets begin with iPhone. Jailbreaking iOS is the process in which the limitations put by Apple are removed and then you can do stuff that’s otherwise impossible on an out of the box iPhone. The jailbroken iPhone is capable of installing apps not available on the App store and install themes not supported by Apple Inc. You can go as far as support for the extensions that are not supported at all as a format by Apple. In order to jailbreak an iPhone, you are required to install a custom kernel (yes, this too is based on Linux as underlying platform) to grant unrestricted access to the apps underneath. All this is possible while the iOS users still have seamless access to the App Store and iTunes.
Android rooting however, differs significantly in these regards. Apple’s iOS is proprietary, meaning you cannot make changes to actual source code. Android however is open source based, modifications and customizations are the essence of this operating system. Third party apps find their way towards development to a much more extent than the iOS apps. Basic functionality is already available in the stock android as the jailbroken iOS device users can only expect to get after jailbreaking process is accomplished. Android phone rooting is much more vast and fruitful in the sense that it not only allows the removal of restrictions imposed by the device manufacturers and the carriers, but it gives a seamless, full rights access to alter the system level files, which could be potentially dangerous.
You can get a modified version of your own android developed as per the customizations desired, however jailbroken iOS devices still have no root permissions to play around with system files, only to unlock certain impositions posed by Apple as restrictions. Additionally, it is possible for the root users on android to flash their ROM and get more or less access to the entire operating system within. This is something that is virtually impossible to accomplish on iOS devices. So jailbreaking iOS is up to a certain level of freedom, whereas android rooting is much deeper and full of control for the apps as well as the android users.
Not only the rules could be altered and tweaked on the root android systems, but it is also possible to like break the rules and make your own rules. Google has realized the power of rooting their devices, hence many devices are readily shipped with unlocked boot loaders to make the process of android rooting much simpler. Apple, on the other hand, is nothing with its jailbreaking that is not at all recommended and opposed by the manufacturer. While android rooting could damage the device if great power available is not handled with certain degree of responsibility, iOS devices are much safer comparatively after jailbreaking.
