redsn0w

Just one day after Apple's release of the iOS 4.2 firmware update, iPhone Dev-Team has made public the first updated jailbreaking tool for Mac OS X and Windows. Redsn0w version 0.9.6b4 can be used immediately for those who are not concerned about using the ultrasn0w unlock. iPhone 3G and older iPhone 3GS users will be happy to know that the jailbreak is untethered.

For newer iPhone 3GS and iPhone 4 users, this version currently requires a computer to boot into the jailbroken state. The iPhone Dev-Team is working with @comex on a fix that would untether the iPhone 4 jailbreak once and for all. Unlockers can expect a new version of ultrasn0w for the iPhone 3G and iPhone 3GS as early as next week.

Here we go again. With Apple's release of iPhone OS 3.1 the iPhone Dev-Team has been busy getting jailbreak and unlock solutions ready. The first of these software packages is Pwnage Tool 3.1 for Mac OS X.

The current version is available directly from the iPhone Dev-Team and supports the first generation iPhone and the iPhone 3G. The Dev-Team is still working on software for Windows and the iPhone 3GS.

Apple released the iPhone OS 3.0.1 firmware update the other day to fix an SMS security flaw. This has rendered purplera1n useless, and creator Geohot has abandoned the project for now. That being said, redsn0w from the iPhone Dev-Team still works.

There's one thing to look out for when using redsn0w to jailbreak 3.0.1. After updating to the official 3.0.1 through iTunes, running redsn0w will ask for the IPSW file to use for jailbreaking. Select the 3.0 IPSW, not the 3.0.1 version you just installed. For owners of the iPhone 3GS or a newer 3G, you may not already have this file.
