Jailbreaking and Unlocking procedure require a few tools, one for the jailbreaking part and one for the unlocking part. All those tools are distributed for FREE, so if you find online companies that provide jailbreaking assistance for a fee, stay away! You need to follow a few steps in order to prepare your iDevice and computer for the jailbreaking and unlocking process.
Prepare for Jailbreaking – Computer!
Jailbreaking can happen with a number of tools, but the most popular for the time being are the Redsn0w and the Evasi0n jailbreaking tools. Both of them are very easy to use, but you need to be sure that you downloaded the correct version.
Redsn0w is only supported by Windows and Mac OS machines, but with a few tricks you will be able to run it on Linux machines as well. There is not an official Linux version though, so to complete your jailbreak quickly, make it on a Windows/Mac OS machine. Evasi0n tool has been released in three versions, Windows, Mac OS and Linux. It is the only tool that can perform an untethered jailbreak to iDevice with 6 – 6.1.2 iOS versions, but NOT the 6.1.3 iOS version.
Both of those tools can be downloaded from their official websites, FREE of charge. They are virus free and the whole jailbreaking procedure will take around 10-15 minutes.
iTunes is also a software that needs to be up-to-date while performing a jailbreak. iTunes is distributed by Apple and you can download it through their official website for FREE (Probably the only FREE thing you can find!).
Prepare for Jailbreaking – iDevice!
Not much preparation is required from the iDevice point of view. You will have to connect your iDevice with the USB port of your computer and before the Jailbreak, you will have to put it into the DFU mode (Pressing Sleep and Hold buttons). This procedure is the most difficult one (you need to be a little accurate while pressing the buttons), but you will be able to see the instructions on the screen of your Jailbreaking tool.
Prepare for Jailbreaking – How much time the whole procedure will take?
The jailbreaking tools are not very large, which means that with a good internet connection you will download it in less than a minute. No installation is required, so you will be able to launch it as soon as you download it. iTunes is a bit larger and it might take you up to 5 minutes (depending on your internet connection). For the Jailbreaking procedure, you will need the IPSW file of the iOS version you want to jailbreak, which is a large file (Around 700Mb).
The jailbreaking procedure itself, will last about 10 to 15 minutes. This means that if you have a very good internet connection, the whole procedure can take up to 30 minutes!
