Unofficial PwnageTool Bundle to Jailbreak iOS 4.0

It doesn't change the baseband you already have. So if it's unlocked it will remain unlocked. Unless you know exactly what you're doing, would advise waiting for the official iOS 4 from Apple (GM will be updated) and Jailbreak from the DevTeam. It wont take long.

Good job!!! Can we get a tutorial

You have to be the most stupid person on earth to release a jailbreak for OS4.0 before the release of the Iphone 4G.

I don't know, I think your post probably tops that making you the stupidest person in the world. They've release an iOS 4 Jailbreak after the developer release of the Gold Master of iOS 4. Sounds pretty logical to me, but your the stupidest person in the world so wouldn't expect you to understand. (This is mostly tongue in cheek but also a little bit serious)

This only applies to already-jailbroken devices, no new exploits are being revealed in this jailbreak.

does is unlock 3gs baseband?12.05.1

It's a JAILBREAK, not an UNLOCK. If your not good with copying and pasting and Terminal stuff, don't even try it.

Um, read it again..it says Jailbreak

but if this is a pwnagetool then it doesn't upgrade your baseband. So that should mean you still can use ultrasnow. Or i'm I wrong?

yup, you're wrong. It doesn't hacktivate.
