Earler we reported that Redsnow 0.9.6 b3 is coming soon and finally it has been released. This latest version allows users to install their own custom bundles like OpenSSH, OpenSSL and basic APT installer programs.
Redsnow 0.9.6 b3 also brings support for iOS 4.2.1 GM build. However this release still includes the same old cydia app which is not compatible with iOS 4.2.1.
Here is the complete official update note:
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.
The new redsn0w 0.9.6b3 is available at:
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:
redsn0w has also been updated to recognize the 4.2.1GM IPSWs. *However*, as noted above, the 4.2.x jailbreak is not yet untethered! That means until someone like @comex comes up with a way to untether it, you must use redsn0w (or a similar utility) to boot your device until a jailbroken 4.2.1 state.
With the above redsn0w and SSH bundle, jailbreak developers and tinkerers can jailbreak and SSH into their 4.2.1 devices, provided they’ve done a tethered boot (using redsn0w’s “Just boot tethered right now” option).
Note: The Cydia that’s included in 0.9.6b3 is the same one as in 0.9.6b2, and so it will *not* work on 4.2.1. Don’t try installing it on 4.2.1! Instead, use the SSH bundle, or compile Cydia on your own.
