New firmware 4.0.2 is out ... it CANNOT be jailbroken

Just a quick note to let you know that 4.0.2 firmware was released yesterday. Note that while this firmeare version DOES fix a serious security risk ( the one that the current jailbreak utilizes ) it is not currently jailbreakable.

My suggestion to those jailbroken on 4.0 or 4.0.1 firmware is to NOT upgrade to 4.0.2 but to go into Cydia, search for saurik's "PDF Patch", and install it. This will ensure that :

1) Your iPhone will still be running jailbreakable firmware ( you never know when you need to re-install 4.0 or 4.02 and require a re-jailbreak ), and

2) Your iPhone will be secure against any malicious uses of this firmware vulnerability

That's it for now.

New jailbreak for 4.x firmware!

As of this afternoon there is now a jailbreak to handle all iPhone models on 3.x firmware and higher.

I have jailbroken ( but not unlocked, that's coming soon ) my iPhone 4 without issue - some people are reporting Facetime problems.

I have jailbroken and unlocked my 3GS running 4.0.1 firmware without issue.

For now, I'd say hold off for 24 hours and let the issues, and solutions, come out. A quick update for the jailbreak will probably be published.

However, I'd say that if you're feeling brave and have a 3GS on 4.x firmware, go ahead and jailbreak and unlock. Feel free to contact me if you'd like me to do this for you.

I'll post an update when/if an update comes out that fixes any issues.

UPDATE : All issues ( Facetime and MMS ) have been sorted out now, I think that it's safe to jailbreak and unlock now. Note, though, that there is still not an unlock for the iPhone 4. It is currently undergoing some final testing, then it'll be released. However, for the 3GS ... we're ready to go!

UPDATE : It appears as if the unlock for the iPhone 4 will be released in 48 hours ( it's 10:35 PM MST right now ).
