iPhone OS 3.1: Jailbreak and Unlock issues

Posted on Thursday September 10th, 2009 / 20:53

Σε συνέχεια του προηγούμενου  δημοσιεύματος περί Jailbreak/Unlock του iPhone OS 3.1 ας δούμε τι ανακοίνωσαν μερικοί από τους σημαντικότερους εκπροσώπους της iPhone-κοινότητας.

Ο Sauric, δημιουργός του Cydia, δηλώνει ότι:


If you upgrade to 3.1 you will not be able to unlock your phone at this time, and maybe forever after.

Upgrading your iPhone 3G(S) to 3.1 may make it unable to be jailbroken ever again. It is hoped that in the near future, an exploit will be found for 3.1. If you must upgrade to 3.1 you should only do so if you have an ECID SHSH “on file” with Cydia. It is assumed (but not yet known) that this information will be usable to allow one to downgrade to 3.0 at a later point.

Note: Apple will not allow you to downgrade to 3.0 firmware anymore. They have taken this ability away from us. Users that have agreed to let me hash their keys with Apple and store them will hopefully be able to downgrade to 3.0 soon, but users who did not do this (even if they have saved some information themselves) will have to wait for someone to build something to use that information (my hashes are more complete). Note taht not everyone got these from me that asked :1500 people asked after the window closed. An additional 250 were even told that they got hashed correctly, when they had not(I have fixed the display that it broke).

I wish i could have gotten this service out sooner, but a bunch of issues kept aligning to make it not come together until Sunday :( . From all of us to Apple: we don’t like you either. :(

Ο BigBoss σε αντίστοιχο κλίμα δηλώνει τα εξής:

So as of today, Apple has stopped signing 3.0 and 3.0.1 restore files. That means that if you have a 3GS iPhone you cannot restore any firmware other than 3.1. If you are happily jailbroken today and something goes wrong you are pretty much screwed. Here is a summary:

1) If you have an iPhone 3G or 2G, you are fine and should be able to restore.

2) If you have a 3gs, you can only restore 3.1 (and kiss your jailbreak good bye). If you did not get an IBSS/IBEC signature before now and you restore, you may never be able to jailbreak again.

3) If you have an iPhone 3GS and you used Cydia to save your TSS or did purplera1n or similar a while back and saved your IBEC, then you will be able to restore in the near future, but you must wait for someone smart to write a utility that will let you do it. Chances are good that such a utility will come out in a couple days. If you can be patient and wait, do so. No one wrote this utility prior to this because we were not sure if Apple would actually stop signing 3.0 – only that they *could*.

It looks like an exploit has already been found in 3.1 firmware so it sounds like a jailbreak will be possible, but again, hold out for a bit.
