iPhone Dev-Team Explains 3GS Jailbreak Delay and How to Prepare

Posted June 28, 2009 at 7:52pm by iClarified
The iPhone Dev-Team has posted some details on the iPhone 3GS jailbreak delay and what you must do to prepare for it

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.

Instructions on how to do this can be found here: Windows, Mac

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”!

The pathetic part is that apple is spending a lot of money developing ways to stop the jailbreaking of the iPhone and jailbreaking doesn't even effect them fully except when people crack apps and don't pay for them. If a ton of people in the world won't buy an iPhone or won't buy a new iPhone if it can't be jailbroken, that will only hurt them. If you didn't take away choice in the first place you wouldn't have to spend so much time trying to take it away from people, wake up apple!!!!

If i get an iPhone by next week, will the Prep still be good? Do we still have time to get it ready? if so how long would you say? i only get my phone next week. Ben

I'm not sure went Apple will update the 3GS, but it defintely won't be in the next week. You will be fine, man.

Sigh It looks like we are in the very edge. Apple has developed a stronger broom and it seems like we might be at the very edge of our table. I hope this isnt the end. They really are against this. Damn

As long as we prep for the jailbreak, via Purplera1n, we should be fine. Their firmware will never be completely bullet-proof.. nothings perfect
Simon - June 28, 2009 at 11:32pm
But cant the Apple come over to iPhone-Dev website and look at what we are up to?
Nick - June 29, 2009 at 8:48am
They could, but unless they have the program and know how the Dev-Team is jailbreaking the iPhone 3GS it's a guessing game for them.

I would like to there really LEGALLY UNLOCKED IPhone ( for any version)? If so, is that means, I can use any SIM and will no longer be needing for JAILBREAKING/UNLOCKING?
Javier - June 28, 2009 at 9:22pm
There are factory unlocked version. I have 3G 8GB Black factory unlocked, and I upgrade to the 3.0 without locking the phone but then I had to do the JailBreak because I wanted the applications MCleaner, Backgrounder, Notifier, Cycorder... and tons of others customatization that Apple would not allow.... But if you do not need these applications, then you do not have to jailbreak it.
Simon - June 28, 2009 at 10:18pm
Wait where do you buy already unlocked iPhone?
francochelsea - June 29, 2009 at 2:58am
I bought a 3GS in Italy and by law they have to be unlocked!!!
Alex - June 28, 2009 at 8:03pm
Great! Really hoping they can fix the push issue if not it's fine I have the 2G and have MMS enabled which is enough for me and the video recording is next.
FadetoBlack - June 28, 2009 at 8:24pm
Yea, you Americans don't have mms yet, hey? Rogers wireless, here and Canada came prepared, :-p the mms feature is amazing! By far the best new feature of 3.0!
FadetoBlack - June 28, 2009 at 11:11pm
If you pay over $100 a month on your bill you get $500 off the non-contract price if you are upgrading your phone.. I got my 16GB iPhone 3GS for only $199, so I have no idea what you are talking about.. and I find having MMS a lot more handy than emailing my pictures and videos. And, IMO, Bell has the worst reception, and Telus just peforms poorly in general.
