greenpois0n-rc5

The Chronic Dev-Team has finally released the new version of Greenpois0n, which features a full untethered jailbreak for iOS 4.2.1. No SHSH blobs needed. The exploit used has already been patched in iOS 4.3, so it not work on future iOS 4.3.

Unlockers: do not update to stock iOS 4.2.1. You should keep your baseband version. Wait for new version of PwnageTool.

Apple disabled jailbreak detection API in iOS 4.2



jailbreak API

Apple has reportedly disabled its jailbreak detection API through iOS 4.2 software update. The API helped third-party mobile device management (MDM) applications to check for unauthorized modifications of system files. Apple's jailbreak detection API provided MDM applications direct access to iOS system information and was able to ask the operating system directly if it had been jailbroken. Jailbreak exploits typically change a number of operating system files, and exploit one or another low-level OS features to let users directly load their own or third-party applications.

QuickTime version updated to 7.6.9



qt769

Yesterday Apple released a new 7.6.9 version of QuickTime media software, which has 15 vulnerabilities patched, including issues with FlashPix, PICT, GIF and JP2 images and AVI, MPEG, Sorenson, QTVR and other movie files. Most of it could cause an arbitrary code execution in case of exploit or unexpected application termination.

The security update is necessary only for Mac OS X Leopard 10.5 and Windows users, as Mac OS X 10.6.5 already has fixes to the vulnerabilities included.

QuckTime 7.6.9 can be installed through Software Update or by visiting the QuickTime website.

RedSn0w 0.9.6b4: jailbreak for iOS 4.2.1 released



Redsn0w-096B4

DevTeam worked hard for the last several hours and released jailbreak tool for iOS 4.2.1. It is redsn0w 0.9.6 b4.

As usual we remind all ultrasn0w unlockers please stay away from this official firmware. Wait for the ability to create custom 4.2.1 IPSWs that don’t update your baseband!

New redsn0w 0.9.6 b4 uses limera1n exploit and will successfully jailbreak all devices. The only problem is that it is a tethered jailbreak, which means you will have to plug it to a computer and rerun redsn0w on every reboot. This so called tethered or semi-tethered jailbreak. This condition applies to iPhone 3GS (new bootrom), iPhone 4, iPad, iPod touch 2G (MC model), iPod touch 3G and iPod touch 4G. Hackers are working hard to create untethered jailbreak for these devices. To use future untethered jailbreak you need to save SHSH keys for iOS 4.1 using TinyUmbrella utility or directly in Cydia.

Old devices like iPhone 3GS (old bootrom), iPhone 3G and iPod touch 2G (non-MC model) can be jailbroken-untethered right now using this latest version of RedSn0w.

You can download RedSn0w 0.9.6 b4 here.

Jailbreak iOS 4.2: what can we expect?



iOS 4.2 Jailbreak

Next iPhone/iPod/iPad firmare iOS 4.2 is due out soon. What can we expect in terms of jailbreaking 4.2?

Limera1n exploit for 4.2 in most cases is a tethered jailbreak. That means if you have to reboot your device, it will show a "connect to itunes" logo until you run the jailbreak software again.

  • iPhone 3G - will run 4.2 untethered. Redsn0w will be updated.
  • iPhone 3GS - old bootrom will run 4.2 untethered if done via Pwnagetool while updating from 4.1. Otherwise it will be tethered.
  • iPhone 4 - tethered
  • iPod 2G - untethered.
  • iPod Touch 3G, iPod Touch 4G - tethered
  • iPad - tethered.

Tethered jailbreak isn’t that bad for iPads and iPods. But if something happens and your iphone reboots while you’re away from your computer, you cant use the device until you get home and run some tool on your computer again.

We suggest not updating until new expoit will be implemented in new utility.

The community is working on a solution to this to either make the jailbreak untethered or at least semi-tethered. Semi-tethered means the device will at least reboot, but unjailbroken while on the road until you return to your computer.

Images of life inside the iPhone factory



iphone factory

Gizmodo posted shots of dorm blocks, in which Foxconn’s factory workers spend their off-duty lives. Men and women have separate facilities. Eight workers sleep in four bunk beds in a room about the size of a two-car garage. Long shifts, under-exploited exercise equipment, sinks on the balconies, where workers have to wash their clothing and themselves, and tiny televisions (one per a floor) in depersonalized common rooms, this is life at Foxconn’s iPhone factories. Since a spate of eleven suicides earlier this year, every building on the Foxconn campus is draped in netting. It is morbid but seemingly effective; there have been no suicides since the nets were installed in May.
