As far as we know, the Apple’s browser Safari was always the subject of intense criticism for its various security weaknesses.  A couple of days ago Safari got pwned again at the hacking challenge pwn2own. It took the French team consists of specialists of security firm Vupen just a few seconds to exploit an unpatched Safari vulnerability. “We pwned Apple Safari on Mac OS X (x64) at pwn2own in 5 seconds,” they tweeted. Just a few minutes before the contest, Apple released Safari 5.0.4 alongside iOS 4.3. Vupen said that the update 62 vulnerabilities, breaking “some exploits but not all.”  The winners were awarded $15,000 and a MacBook Air. In addition to Safari, Microsoft’s Internet Explorer 8 was also hacked pretty quickly.

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.

You can jailbreak iPhone 4, iPhone 3GS, iPod Touch 2G, iPod Touch 3G, iPod Touch 4G, iPad. Unlike redsn0w 0.9.6 this is untethered, so there is no need to connect iOS device to a computer after restart.

There is only Mac OS X version available. Chronic Dev-Team will release Windows and probably Linux version soon.

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

You can download GreenPois0n RC5 from here.

UPDATE: Please, consider reading our Jailbreak & Unlock FAQ, especially if you have questions or troubles.

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.

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.

This is the tweet from MuscleNerd posted a minute ago. So it is just minutes to wait for new unlock utility ultrasn0w.

UPDATE: New ultrasn0w released! New PwnageTool 4.1.3 released. Read carefully this post from DevTeam first, then reread again!

UPDATE 2: new ultrasn0w 1.2 supports the following basebands:

• iPhone 4: 01.59.00
• iPhone 3G/3GS: 04.26.08, 05.11.07, 05.12.01, 05.13.04, 06.15.00.

UPDATE 3: Step-by-step Tutorial: How to Jailbreak and Unlock

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.

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.

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.

MuscleNerd, a hacker from DevTeam, recently published a screenshot of anticipated jailbreak utility PwnageTool 4.1. It will support iOS 4.1 and will be able to preserve old baseband for unlockers, who have not updated to iOS 4.1.

From the screenshot we can tell that PwnageTool 4.1 will support:
