o Whom May Concern, the Dev-Team Blog has release a new redsn0w version 0.9.6b4 (based on Geohot’s Limera1n bootrom exploit) which can jailbreak the latest Apple iOS 4.2.1 (added with new feature like AirPrint and AirPlay to all iOS devices) which released on Monday. Here go the step:

Step 1. Back Up Your SHSB Blob
It’s advisable to backup your SHSB Blobs for the future, before you use any new jailbreak as you could easily restore it back to the original condition prior to the jailbreak if anything happen. For the step to back up the SHSB Blobs, please follow the guide as show in the video: How To Backup SHSH Blobs/Files On iPhone/iPad/iPod Touch JAILBREAK SPIRIT
Step 2. Please make sure that your iTunes is of the revision 10.1 before you proceed to the iOS 4.2.1 update. You can download iTunes 10.1 (http://support.apple.com/kb/DL1103 ) at Apple website or you can update your iTunes through the apple software update.

*Notes: iOS 4.2 is compatible with the iPhone 3G, 3GS, and iPhone 4, the iPod touch 2nd, 3rd and 4th generations, and the iPad.
