redsn0w+limera1n fun for Jb iOS4.2 on Win and Mac

It looks like geohot’s recent limera1n exploit for iPhone3GS/iPhone4/iPad/ipt3g/ipt4g/atv2g will be very beneficial to jailbreakers and unlockers for the next few months (at least).  geohot’s limera1n program and the alternative greenpois1on program both use his same exploit (although greenpois0n refuses to tell you that, FWIW), and hopefully SHAtter can be saved for some later device.
In the meantime, we’ve also incorporated the limera1n exploit into redsn0w.  But we’ve added a few extras:

  • custom bootlogos for iPhone3G/iPhone3GS/iPod2G users (with qualifying bootroms)
  • an option that implements the “DFU” button in PwnageTool.  This button (which you can use from Windows) lets you prepare your device for a custom DFU.  Even if you’re purely a Windows user, you can get a trusted friend to run PwnageTool over your IPSW to create a custom IPSW.  You can now install that custom IPSW on your own Windows box, after you run this redsn0w version.
This latest redsn0w is available at:
For Windows users who have run redsn0w and chosen “Just enter pwned DFU mode right now”, your device is now completely vulnerable.  Running iTunes and selecting a custom IPSW from PwnageTool (choose it by pressing Shift+Restore)….you’ve now convinced your device and iTunes to restore to a custom firmware.  Congratulations!
If you are timid about software and running these programs…please just wait!  Don’t jeopardize your carrier unlock for a firmware upgrade.  Wait for even easier methods than this latest redsn0w release.
Update #1:  Today Apple released to developers the GM seed for 4.2.  Tinkerers will find that yesterday’s redsn0w jailbreaks today’s 4.2 GM seed, simply by pointing redsn0w at the 4.1 IPSW (rather than the 4.2 one).   Right now it mostly only makes sense for JB app developers to do that because many apps (including Cydia itself) need to be updated for 4.2.  However, if all you want to do is enable afc2 (to use iFunBox or other file browsers), or to tweak settings like Battery % and Homescreen wallpapers, then go for it (if you have valid paid access to the GM seed).  Be sure to uncheck the Cydia box, though!  Ultrasn0w unlockers should stay very far away from this!!
