Unlock, jailbreak and root are just some of the terms used in the world of mobile devices. In the following we will briefly explain what each one means.
Mobile devices purchased at an operator with a contract or bundled generally come locked to a network of the same operator, and allow for the use of their SIM cards. For example, a mobile device purchased at T-Mobile will not work with a SIM card VIP mobile operator. These devices have locked the firmware that is specific to the mobile network operator. The main reason why operators locking devices is that they want as many users on it for a long time. When buying a device for operators get several years of warranty but this warranty is valid only if the device is unlocked. At the expiration of warranty, or a certain time, operators are required to unlock the device for free.
Of course, mobile devices can be unlocked (decoded or unlock) before the expiry of the time just keep in mind that to lose the guarantee. You can do this in the following ways: by entering a certain code that you can retrieve through specialized websites (eg: cellunlocker, globalunlock, thephoneunlockers) using special cables for decoding, installing or upgrading basic software that is already unlocked and with the help of a special SIM card that you can find by advertisements.
Jailbreak or iOS Jailbreak is a way for a user to bypass any restrictions set by the company Apple. Apple’s operating system for mobile devices, iOS, is protected in a way that it can not delete, add, copy, or modify certain files.
Jailbreak not unlock that was mentioned earlier, but the jailbreak removes the above limitations and provides the ability to install applications that Apple’s App Store is not approved, and they proved to be useful, and the possibility of changing the appearance of some parts of the operating system. So with the help jailbreak can modify backgrounds, icons, applications, etc.
Since the jailbreak is presently not considered staying illegally, you can always be removed from the iPhone should not lose anything. Of course, considering that the jailbreak opens up some new opportunities and to move some limitations, which are often associated with safety devices, after a jailbreak of the responsibility for the proper functioning and safety of switching to the user.
The most common alternative to the Cydia App Store that provides a number of free and commercial applications, tweaks and themes that are otherwise without a jailbreak would not be used. As long as the user continues to rely on Cydiene recommended repositories should not be a problem. Jailbrek is legal, but not 100% sure. Be careful you do jailbreak at your own risk.
There are other variants of the lock when the device is activated some kind of protection, and you need a security code or a gesture to gain access to phone functions. Then it is most necessary to reset the device, which of course you will lose all data on the device.
While the term is used to jailbreak iOS devices, root used in devices that run the Android operating system. Root comes from the world of Linux and Unix root where a single user with admin privileges – what with all the powers of the whole system. Android is based on Linux, so roots in the context of Android relates to getting admin rights despite the intention of the device manufacturer to disable. So you have full root access to the operating system, so you get the ability to add, change and delete the part of the Android operating system. Manufacturers usually preclude administrative privileges on devices using the excuse that so only ensures the proper functioning of the device and the user can not set anything wrong and thus damage the device or software.
For most manufacturers, the root device lose warranty, and besides, you can break down and fully mobile. Such failures are often referred to as “bricks” (brick = brick, turning your device into a brick). There are two types of brick – the first soft brick, which means that the phone can be repaired by re-entering the factory software, while hard brick completely unrecoverable.
But why take root Android mobile device? Root result in new functionality, such conversion devices in a wireless access point, new visual themes that can completely change the look of cell phones, backup the entire phone, install software on the SD card, delete unnecessary applications that come with the device itself, putting the newer version of Android not supported by the manufacturer or delayed by a year with the update, various modifications of the acceleration device, etc. Some of the options listed here come with newer versions of Android provided by the manufacturer is willing to supply the older device, bringing the number of reasons for the reduced roots.
