Ipwndfu

ipwndfu is a jailbreak utility from axi0mX, released on April 11, 2017. It uses the alloc8 Exploit to achieve an untethered jailbreak or downgrade on both variants of the iPhone 3GS. It also contains many useful, DFU interactions for researchers. The program is mainly used to put the device in pwned dfu mode since programs like redsn0w is not compatible with alloc8 and is currently unstable trying to jailbreak certain devices.
