Dev Team Demos iPhone 3GS UltraSn0w Jailbreak

Sébastien Page ∙ July 3, 2009

Shortly after GeoHot released his PurpleRa1n jailbreak, the Dev Team posted a video showing a jailbroken iPhone 3GS running the UltraSn0w unlock.

Our ultrasn0w program uses the at+xlog crash as an injection vector of our unlocking payload — and it does so on the 3GS in exactly the same way as on the 3G! But this injection vector will be lost if you update to 3.1 using the official Apple IPSW, which updates the baseband. So stay away from official 3.1 IPSWs until we release the tools that let you update the firmware without updating the baseband.

The Dev Team is still waiting on the OS 3.1 update to release its jailbreak.

iPhone 3GS Jailbreak With PurpleRa1n

Sébastien Page ∙ July 3, 2009

Not even a week after showing solid proofs of a successful iPhone 3GS jailbreak, GeoHot officially released PurpleRa1n, a tool to jailbreak the iPhone 3GS. The Dev Team planned to release their 3GS jailbreak after the OS 3.1 update but GeoHot just couldn't wait.

Normally I don't make tools for the general public, and rather wait for the dev team to do it. But guys, whats up with waiting until 3.1? That isn't how the game is played. We release, Apple fixes, we find new holes. It isn't worth waiting because you might have the "last" hole in the iPhone. What last hole...this isn't golf. I'll find a new one next week. Also your purplera1nyday files ensure that you can always get back to a jailbroken state, so if you have it it's just a matter of tools.

Before going through a short PurpleRa1n tutorial, there are a few things you need to know:

This is a beta release with some major hiccups. It is not stable at all. PurpleRa1n only works with 32 Bit Windows XP SP2 works fine on Windows and Mac You must have the latest version of iTunes installed The jailbreak is incomplete and many apps won't work (ie WinterBoard)

Prepare Your iPhone 3GS For Jailbreak

Sébastien Page ∙ Updated January 23, 2016

The Dev Team posted a message yesterday suggesting that iPhone 3GS owners should prepare their device for jailbreak.

Remember we warned you to stay away from any updates to 3.1 if you want to be able to jailbreak or unlock your 3GS.

Well this is an additional message to all you 3GS owners that would like to jailbreak your device sometime soon, but this advice comes with a warning! A warning that if you accidentally upgrade to 3.1, you will not be able to use Ultransn0w, so please re-read and double check this warning at the bottom of this post before proceeding.

During the restore process iTunes nicely keeps these oh-so-top-secret-files in a lovely accessible place for us to copy out and backup, that place? /tmp on Mac OS X or %TEMP% on Windows. Thanks Apple — handy!

The downside to this approach is that you actually need to go through the restore process to get these signed files, which has risks if you are anywhere near 3.1 or 3.1 beta :-)

iPhone OS 3.1 Beta Is Out. Jailbreakers, Stay Away!

Sébastien Page ∙ July 1, 2009

Apple released the 3.1 beta firmware and SDK to developers, which seems to include a few new features such as:

Non-destructive video editing Voice Control over Bluetooth iPhone vibrates when moving icons New APIs to enable third party apps to access videos and edit them "Fraud Protection" toggle Faster boot time

The biggest change is the update of the baseband to 5.08.01.

If you don't care about jailbreaking or unlocking your iPhone, then this doesn't matter to you. However, if you want to keep you device jailbroken/unlocked, you should not update to 3.1 beta, or even the official 3.1 firmware when it's released to the general public.

Like the Dev Team warned us, updating to 3.1 will prevent you from running any jailbreak method, which would make it impossible to unlock.

Ultrasn0w users must stay away from any firmware updates past 3.0 (including today’s 3.1 beta) until we release the tools that let you update the firmware without updating the baseband. For most phones out there, baseband updates are irreversible and you’ll lose ultrasn0w.

This warning does not apply to the iPhone 2G, which uses BootNeuter for the unlock, not ultrasn0w.

My advice is to wait and see. The Dev Team is most likely already picking the 3.1 beta apart. Stay tuned for more updates as they become available.
