Last night Dev Team officially released PwnageTool 4.2 with which we can do untethered jailbreak for iOS 4.2.1. In the article written by the team detailing the news in PwnageTool 4.2, it was mentioned that the exploit used in this version of the application is closed in iOS 4.3, but that the team has another one already prepared. The new exploit was developed by a security expert who claims that he will publish the untethered jailbreak solution for iOS 4.3 as soon as this version of iOS is available through iTunes. The Dev Team recognizes his work, so everything is as simple as possible and we will have untethered jailbreak for iOS 4.3 shortly after its release.
Until then, don't forget that you have here tutorial for untethered jailbreak using PwnageTool 4.2.
