Obviously notorious George Hotz has managed to get all 7 SPUs of the Playstation 3’s CPU under his control. This means although he cannot access the CPU’s root key, he now can decrypt everything that’s going thru these SPUs like datastreams of (encrypted) commercial games.
The PPU is higher on the control chain then the SPUs. [...]

Egyptian neurosurgeon Sherif Hashim seems to have found something very interesting. He found a way to actually crash the iPhone’s baseband 05.12.01 of the latest firmware update 3.1.3.
MuscleNerd of the iPhone Dev Team has confirmed this bug. Though the iPhone Dev Team posted later today that they cannot tell if this bug actually leads to [...]

From the iPhone Dev Team’s Wiki:

What is it?
A cross-platform jailbreaking, unlocking, and customizing tool for iPhones and iPod touches. Customizations include boot logos, recovery logos, and “verbose” boot. It’s a standalone program that doesn’t use iTunes (no custom IPSWs are involved).
The download links are at the bottom of this page (but please read the whole [...]

Notorious iPhone hacker GeoHot has succesfully circumvented the Playstation’s security system. According to his latest blog entry, he has dumped LV0 and LV1 code, thus allowing him to (theoretically) run code on the processor, bypassing the hypervisor.
The Playstation’s hypervisor is intended to run third party software (like Yellow Dog Linux) on a virtualized level, thus [...]

We prepped a list of current scammers making a business modell out of other [...]

Some hours ago GeoHot released his unlock answer to the latest baseband of Apple’s iPhones. Now with BlackRa1n jailbreaking of firmware 3.12 and with BlackSn0w unlocking of baseband 05.11.07 is a hitch for almost everyone. Kudos fly out to notorious GeoHot.

George Hotz – by now almost any iPhone user should know that guy – hacked the latest baseband firmware 05.11.07. The unlock will be named BlackSn0w, well …
That means all carrier or SIM locked iPhones around the globe running this latest firmware can be used with different SIM cards from different carriers. Thus making holidays [...]

Today notorious GeoHot released a standing new jailbreak tool called BlackRa1n. BlackRa1n is currently only available for Microsoft Windows. It is supposed to jailbreak any 3.x based iPhone or iPod touch. No matter if you’ve jailbroken before or not.
BlackRa1n is fairly self explaining and straight forward designed. It’ll bring your iPhone or iPod Touch automatically [...]

GeoHot today posted a photo of a jailbroken iPod Touch running iPhone OS 3.1. He eventually made it. As of now there is no more information available, but it is likely that this is the approach he and the Chronic Dev Team were talking about.

What has happened so far
Some irritation is going on in the Apple hacking community. On the one hand GeoHot today announced that there will be a tool that will allow jailbreaking all iPhones and iPod Touchs, but as he wished to perform further tests he didn’t tell anything about the procedure.
The Chronic Dev Team on [...]

Update July 5th, 2009: GeoHot now also provides a Mac OS X version of the jailbreak tool. Windows and Mac versions ready for download at purplera1n.com…
That’s it with the 3.0 firmware and the iPhone jailbreaks. Apple has been beaten again. This time by GeoHot. Although the iPhone Dev Team seems to have their programs already [...]

GeoHot posted a picture showing that he managed to run custom commands on iBoot. This seems to be the first major step for a jailbreak. Moreover GeoHot also managed to find the key for the Ramdisk while MuscleNerd of the iPhoneDevTeam obviously has already found the vfdecrypt key.
All this is good news. Anyway aswell as [...]

We’ve recently reported that exploits can be applied to the baseband bootloader 5.8 to install any bootloader. Now a working exploit has been released via Cydia.
As we have not tested this program we strongly recommend not to try this for two reasons: first it seems this package is in violation of Apple’s copyright, as it [...]

George Hotz – well known to the iPhone scene as GeoHot – has put some efforts into analyzing the  behaviour of the bootloader 5.8 that is running in many iPhone 3G’s. He found the signature checking of the bootloader is buggy. By exploiting this bug we are now able to up- and downgrade the bootloader. [...]

GeoHot just granted the world an insight into his current work project. It is called EDA and it almost looks like IDA (that btw also includes an iPhone debugger), but EDA seems to go a little further in case of simulator/dissassembler terms.
Geohot says the EDA simulator to:

include version control
allow graphical comparision between different versions of [...]

iRan is a tool that makes use of Geohot’s findings dated last year about the iBoot. He found out that in DFU mode it offers a full interactive shell. But it took almost a year to allow execution of non-signed code. The iPhone Dev Team now used this in their Pwnage Tool 2.0 for expanding [...]

Although we didn’t get our hands on a new iPhone 3G yet, things are as expected: the iPhone 3G uses a new bootloader for its baseband modem as confirmed by Geohot.
Bootloader versions from the “old” iPhones
As far as we are aware the there are those 3 different bootloader versions known on old iPhones:

3.8 (very rare)
3.9 [...]

George Hotz just modified iPhone’s Bootloader 4.6. With those results:

no signature checks
Secpack update check removed
full write access

But since the original bootloader is legally owned by Apple you will not be able to download this bootloader. But he said he would provide patches… More information to be found here…

George Hotz – the first one to unlock an iPhone ever (via the highly newbie incompatible hardware testing point method) – did it again. New iPhones being shipped beginning at latest in week 45 can now also become unlocked very comfortable on the software way. More information in George’s own Blog entry. I’d really like [...]
