GreenPois0n RC5 released: untethered jailbreak for iOS 4.2.1


The Chronic Dev-Team has finally released the new version of Greenpois0n, which features a full untethered jailbreak for iOS 4.2.1. No SHSH blobs needed. The exploit used has already been patched in iOS 4.3, so it not work on future iOS 4.3.

You can jailbreak iPhone 4, iPhone 3GS, iPod Touch 2G, iPod Touch 3G, iPod Touch 4G, iPad. Unlike redsn0w 0.9.6 this is untethered, so there is no need to connect iOS device to a computer after restart.

There is only Mac OS X version available. Chronic Dev-Team will release Windows and probably Linux version soon.

Unlockers: do not update to stock iOS 4.2.1. You should keep your baseband version. Wait for new version of PwnageTool.

You can download GreenPois0n RC5 from here.

    у меня на iPhone 4 с прошивкой 4.1 стоит родной модем 01.59.00

    Dre@meR прав!
    у меня модем не обновился, когда я на 4.1 обновлялся.
    у обычной iOS 4.1 версия модема 2.10.4, а она не разлачивается.
