ToolJail is designed to help iPhone newbies jailbreak and unlock their iPhone and iPod touch. It contains all the necessary jailbreak and unlock instructions, along with how-to’s on DFU and Recovery Mode, downgrading firmware, and direct download links for all the necessary tools required.
ToolJail is similar to F0recast, which lets you enter the basic information about your iPhone or iPod Touch and then it will report back whether or not you can jailbreak and unlock your device. The best part of this tool is that it even provides an how-to guide in case you do not understand something and want to know in detail.
