The iPhone Dev Team have updated their redsn0w jailbreak and ultrasn0w carrier unlock tools to work with the iPhone 3GS, citing the release of rival app purplera1n as forcing their hand. The Team had originally intended to wait until iPhone 3GS adoption was more widespread before distributing their tools, in the hope that it would give Apple less time to close the security hole on which the unlock depends.
“We realize we upset some folks (e.g. existing 3GS owners) with our earlier announcement that we wanted to hold onto the 3GS iBoot-family hole until 3.1 was out. Our aim there was to get as many people as possible onboard (within reason of course) before revealing the hole, since Apple will fix it immediately. But all of that became moot when the purplera1n release was made, since it uses the same hole” iPhone Dev Team
Those wishing to unlock their iPhone – and keep it unlocked – are still being warned to avoid Apple’s official baseband updates. The Cupertino company has apparently stepped up its efforts to remove loopholes such as the one which enables this latest version of ultrasn0w.
Going by the comments over at the Dev Team blog, however, Apple retaliation is not the only problem some users are facing. Some iPhone 3GS owners are experiencing poor signal reception after unlocking, or an inability to connect to WiFi networks, while others claim their handsets have been left bricked or show significant battery drain. Now seems as good a time as any to warn that Apple are unlikely to perform warranty repairs on any iPhone they believe has been tampered with, so you attempt a jailbreak or carrier unlock at your own risk.

The iPhone Dev Team have announced that they are delaying the release of the updated ultrasn0w iPhone 3GS jailbreaking and unlocking tool. In a post on the Team’s blog, they detail the nature of the exploit used to jailbreak (and then unlock) the 3GS, a loophole which Apple could readily close once it was made public.
“Here’s the critical point, the reason why we’re delaying our version of the jailbreak: Once the jailbreak is out, Apple will fix the iBoot-family bug we use to accomplish it. They will simply stop signing the old iBoots and only sign the fixed ones. If you bought your phone after Apple has done this, there’s nothing you can do…the jailbreak isn’t going to work for you.” iPhone Dev Team blog
According to the Team, the exploit depends on an iBoot-family bug, which can only be addressed if users have a signed iBoot-family img3 from their own device. This contains their ECID, a unique chip identifier different on each iPhone 3GS. If Apple discover the loophole, they could update the smartphone and refuse to sign any old iBoots; then those users would not be able to jailbreak or unlock their handsets.
The Dev Team are counting on an imminent iPhone OS 3.01 update which addresses some of the platforms more buggier aspects, and are waiting until then to see the state of play. They’ve given no indication of when the iPhone 3GS jailbreak and unlock option might be released, a situation that’s prompting no small amount of revolt in their comments.

Owners of the new iPhone 3GS will soon be able to jailbreak and unlock their smartphone, thanks to a five-month-old security flaw in the handset’s baseband. The iPhone Dev Team have verified that Apple have not addressed an exploit known as 24Kpwn that was originally identified in the iPod touch 2G; with it, they will be able to upgrade their ultrasn0w tool to work on the iPhone 3GS.
The loophole arose, the Team believe, because Apple finalized the iPhone 3GS’ bootrom in around August 2008, months before the exploit was identified for the iPod touch 2G. 24Kpwn went on to be exploited in the redsn0w tool, and similar techniques can now be implemented in ultrasn0w.
It will take some time to update ultrasn0w with the new system, but once completed it will mean the iPhone 3GS can not only be loaded with unofficial apps but used with any SIM card. Apple are likely to release a firmware update to try to prevent any damage, so the Dev Team are advising that people avoid baseband updates.
