Yesterday I was telling you about RedSn0w 0.9.5b4, a tool to jailbreak the iPhone 3G running iPhone OS 4 beta 4. Today, Dutch developer Kaatje managed to jailbreak an iPhone 3GS with OS 4 beta 4.

She notes on her blog:

Cydia still has some issues, many applications install but crash, some examples include mobileterminal, sbsettings, five icon dock. I did this only to hopefully motivate the developers to get their applications ready for 4.0 as it is coming very soon and the last thing we need in the community is to have repos full of broken apps! I accomplished this by patching asr, lockdownd, LLB, iBEC, IBSS, iBoot, kernelcache, MobileSafari, Services.plist, and fstab. The binaries were patched with IDA Pro and OxED and were then diffed against the original pwned files with bsdiff to create patch files. I then took the diff files and built a firmware bundle that I dropped into Pwnagetool and updated the cydia tree within Pwnagetool as well. Once this was done, I created a custom ipsw with Pwnagetool, unzipped it, applied a pwned LLB from a pwnagetool generated 3.1.3 ipsw, zipped it back up and restored to my device. At this time I am unable to get my T-Mobile NL sim to work so I downgraded back to 3.1.3 after playing around with 4.0 for a while. I look forward to the release and the official unlock from the Dev-Team.

That’s interesting to see she was able to downgrade back to 3.1.3. Other interesting point is the mention of the “official unlock from the Dev-Team”. If I was a conspiracy theorist, I’d think that the Dev Team already found an exploit to unlock iPhone OS 4 but they’re waiting for the official release to make it available to the general public.

What do you think?

    Of course they are waiting for the official release of OS4. I see it this way: Apple releases OS4 then the Dev Team Releases the Jailbreak/Unlock. We all upgrade and Jailbreak/Unlock our phones. Everybody’s is happy except for Apple! Apple should get the point: there are users who simply want the freedom to do what they want with the phone they paid for. It is no longer Apples phone, it’s MY phone.

    Spirit.

    Thanks, good news!

  • Burge

    Bring on 4.0. The jailbreak world is looking ready to stick two fingers up at Apple again, it might be the best phone but it needs a little modding to make it better.

  • Bill

    Apple should be secretly happy. I would never buy the new version iPhone unless it can be jailbroken. I would much rather stick with my jailbroken 3gs with MyWi. IMO Apple will definitely lose to Andriod units if their new iPhone can’t be jailbroken. Long live Spirit and 3.1.3!

    Is there an unlock yet for iphone 3gs 3.1.3 baseband 05.12.10?

  • Alex

    @ mordib0…not yet. Not trying to be mean but take the time to read because a lot of questions can be answered by taking the time to read other people’s comments.

  • DarkReaper

    Of course she would be able to downgrade back to 3.1.3! That FW version is still being signed by Apple of course, just a plain restore will work! The unlock will undoubtedly have to wait for the OS 4’s offical release.

  • ruffnek

    One would think that Apple has a smirk when considering all the work, discussion, and hype that they get from the jailbreak community. Apple needs to accept that there will be groups of people that want to mod their equipment.

  • Xsn0w

    It’s not a conspiracy, it’s a PLAN!

    What kaatje did not mention is that she prevented her baseband from being upgraded, so that when she downgraded, she could still use the 5.11 bb unlock…

    And ruffneck, I agree, Apple is secretly happy that the jb community exists. And even if they arn’t, imagine what kind of an uprising would occur if they did put a stop to it completely. -@xsn0w
