DevTeam 3GS Jailbreak Status
Wie man bereits gestern, durch einige Twitternachrichten vermuten konnte, hat es das DevTeam geschafft, den Jailbreak, an das iPhone 3GS anzupassen.
Doch wird das DevTeam, den Jailbreak erst veröffentlichen, wenn Apple die nächste Firmware 3.0.1 veröffentlicht hat, um so möglichst sicherzustellen, dass die benötigten Sicherheitslücken im iBoot des 3GS, ebenfalls noch neu ausgelieferten Geräten, vorhanden ist.
Alle die,die das iPhone 3GS bereits in den Händen halten, werden den Jailbreak auch zukünftig durchführen können, dazu fordert das DevTeam alle „Jailbreakwilligen“ auf, das entsprechende ECID Zertifikat zu erstellen (die passende Anleitung findet ihr hier).
Doch ist es, für alle die eine Chance, die ihr iPhone 3GS erst später kaufen können oder wollen. Des Weiteren will das DevTeam sich aber auch noch um Fehler kümmern wie ein sie z. B. bei Push Notifications teilweise auftreten.
We can jailbreak the 3GS right now. But making our jailbreak public at this point in time would benefit relatively few people. It would in fact be detrimental to many more people than it would help. So we feel it’s best to keep our version of the jailbreak out of Apple’s sights for the time being.
If you already have a 3GS phone and have already done a full USB dump or captured your img3’s signed with your ECID, then you’re in great shape. You will always be able to jailbreak. But many people who plan on getting a 3GS do not yet have one. For instance, many people are waiting for their existing contracts to mature to the point where they get a price break on the 3GS. Many people are trying to sell their 3G before they can buy the 3GS. There are parts of the globe where you can’t even buy a 3GS yet! The reasons are varied, but they are many.
The nature of the 3GS hardware allows Apple to stop IPSWs from being usable unless you’ve already gotten the signed chunks they send to you based on your ECID (a unique chip ID). You cannot get these signed chunks without knowing your ECID, and you don’t know your ECID until you’ve bought your 3GS.
The jailbreak requires at least one signed iBoot-family img3 for your device. And that iBoot needs to have an exploitable bug. It’s an all-or-nothing deal…you either have your signed exploitable iBoot ready to use, for now and forever — always jailbreakable — or you have nothing.
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.
It is possible that Apple will find the bug we use without our handing it to them on a silver platter (via a public jailbreak). In that case, we will have delayed our jailbreak for “nothing”. But we’d rather be safe than sorry!
Apple is surely coming out with a 3.0.1 firmware release shortly. They need to fix ultrasn0w. They need to fix some UI issues. 3.0 is buggy and 3.0.1 is coming. We’re going to wait and see what 3.0.1 brings before figuring out the release date for our version of the jailbreak.
In the meantime, we have some remaining 3.0 jailbreak issues to investigate, including push notification. Thanks for being patient with us while we took a 3GS “timeout”!
