You waited patiently for the Dev-Team
to pull together all the developer betas and now it's time for your reward: PwnageTool 4.0 has been released. The latest hack from team jailbreak
works with previously jailbroken iPhone 3GS devices with the old bootrom, all iPhone 3G models, and yes, the second generation iPod touch too. It doesn't work with the original iPhone and other iPod touch models and, as always, there are plenty of caveats and bold print warnings to heed. But if you manage to weave your way into a jailbroken device (as we did with our iOS 4 iPhone 3G using redsn0w) then the latest copy of ultrasn0w will now unlock all basebands released since 04.26.08, including the updated version found in iOS 4. So get cracking kids, and remember, buckle up, back up, and be safe.
: 4.01 has already been released to fix an iBook issue.
