Those of you with Apple’s new iPod touch 4G, or those of you who bought another recent device after the jailbreakme.com exploit was closed, have probably heard about a brand new exploit called SHAtter. The exploit (and payload) was developed by @pod2g a few months after @p0sixninja of the Chronic Dev Team discovered the crash. That team is hard at work bringing you a brand new tool to make use of the exploit. It’s not the sort of thing that can be developed overnight so please be patient while waiting for any announcements from them.
In the meantime, we’ve put @pod2g’s exploit into a beta version of PwnageTool to test the waters. The SHAtter exploit was enough to convince the iPod touch 4G to restore to our custom IPSW. The successful result is shown below! It’s all working: customized Preferences to show battery percentage, Cydia, root shell…the works!
Check out the Dev-Team’s blog for more information and a video of the jailbreak.
