The iPhone Dev Team has just released Redsn0w 0.9.6b3 which brings support for iOS 4.2.1 GM firmware file. The highlight feature of this release is SSH and SSL support which will now allow you to install bundles and packages independent of Cydia, which is currently broken on 4.2.1.

We’ve made some updates to redsn0w to make it easier for jailbreak developers (and tinkerers) to get their programs ready for 4.2.1. As noted in Update #2 above, the public version of Cydia (and MobileSubstrate too!) is not 4.2.1-compatible. redsn0w will now let you install your own custom bundles independent of Cydia (the bundle can actually be Cydia if you’ve compiled it on your own). These bundles can be up to 15MB in size, and should be in the form of a gzip-compressed tar file.

It’s very important that you get the file permissions and ownerships right in your custom redsn0w bundles. To give you a practical example of such a bundle, here’s one that includes OpenSSH, OpenSSL, and the basic apt installer programs

This release is mainly geared towards developers who wants to get their jailbreak-apps ready just in time for iOS 4.2.1 release. The instructions to jailbreak iOS 4.2.1 GM with Redsn0w 0.9.6b3 are exactly similar to the last release. Follow our complete step by step guide posted here to jailbreak your iOS device on iOS 4.2.1 firmware.

Note for jailbreakers:

Jailbreakers can use RedSn0w 0.9.6 beta 2 to jailbreak iOS 4.2 GM, simply by pointing redsn0w at the 4.1 IPSW (instead of iOS 4.2GM/beta). Though, the beta’s and GM version are for developers only, considering not many jailbreak apps/tweaks are working yet, including Cydia which needs to be upgraded for use with iOS 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.

Note for unlockers:

If your baseband is 05.14.04 / 2.10.4, Ultrasn0w unlock won’t work on your iPhone. You will have to wait till iOS 4.2 is released, as the Dev-Team plans on updating the tool after the new OS is released.

ULTRASN0W UNLOCKERS BEWARE!!ULTRASN0W UNLOCKERS BEWARE!! The biggest mistake you can make (and it is a big one!) is lettings iTunes restore to the official IPSW — you’ll lose the unlock and won’t be able to go back! You must use Option-Restore, not just the Restore button by itself. Then navigate to your custom IPSW — not to the stock one! If you accidentally started a restore to the official IPSW, unplug your iPhone immediately before the restore gets to the “Updating Firmware” step!
