(After Red Snow's development team Dev Team released iOS 5.0.1, the green poison development Team ChonicDev Team also released Corona, a tool that can directly and perfectly escape from iOS 5.0.1, which is now imperfect. Therefore, iOS 5.0.1 devices that have been jailbroken imperfectly before can be jailbroken again without using Red Snow. Just download and install the Corona tool through Cydia.)
