3.01固件将发布，iPhone 3GS越狱软件推迟
就在大家都已为iPhone 3GS被破解而欢呼雀跃的时候，iPhone Dev-Team却在其网站上发布声明，称他们也已经完成iPhone 3GS的破解工作，不过基于现在还有大部分人没有买。 另外苹果在iPhone 3GS中多了一层防破解保护，这道防护系统为ECID，简单的说当iPhone 3GS透过iTunes回复或升级时，iTunes会先连接苹果的伺服器，然后取得机体(iPhone 3GS)上的系统签名。换句话说，这个系统辨识数字签名非常重要，如果丢失将导致iTunes验证失败。当然GeoHot也找到将它取出的方法。
用ECID制作的系统签名文件对iPhone 3GS非常重要，所以如果你已经买了iPhone 3GS(在苹果还没堵住漏洞之前)还是立刻制作一个备份的好，以后越狱会用到的(文件制作方法Windows，Mac)。
此外他们还称iPhone OS 3.0固件中有许多漏洞，所以苹果将会在近期发布最新的iPhone OS 3.01固件(修复ultrasn0w超雪漏洞和一些3.0的UI问题)，届时再发布iPhone 3GS的越狱工具。
细节:
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”! 作者: 大口仔 时间: 2009-6-29 11:15
