Just a couple of hours after Apple released the iOS 4.3.1 update there was already a jailbreak solution for enthusiasts and believers, though it was untethered meaning there was a need to the phone into DFU mode and run the boot utility from the computer after every reset.
Hacker MuscleNerd tweeted an important bit of information for jailbreak fans telling the world that i0n1c’s untethered 4.3.x jailbreak is “solid”. After sorting out some general 4.3.x issues as well as Cydia, the untethered jailbreak solution should see the light of day. That is, really soon.
