Charlie Miller has once again won the Pwn2Own contest by successfully hacking iPhone 4 using an exploit found in Mobile Safari to swipe the address book of the compromised iPhone.

With the iOS 4.3 Golden Master hitting dev’s iPhones and iPads the world over, we’ve all been wondering just how much faster Safari is now that the new JavaScript optimizations have been added. The answer? A bit.

Starting from iOS 4.0, Apple completely cut off the support for aging original iPhone EDGE and iPod touch first-generation. Their decision of course was justified because of the low RAM found in these first-gen devices which were released back in 2007.

iPhone developer iH8sn0w has pushed another update to Sn0wbreeze 2.2, apparently with a new solution to fix iBooks issue for devices on which it previously didn’t work.

Chronic Dev Team has updated GreenPois0n to RC6.1 which incorporates fix by Comex for iBooks DRM error after jailbreaking iPhone, iPad or iPod touch on iOS 4.2.1 it with GreenPois0n RC5/6.

iPhone developer and hacker ih8sn0w has released Sn0wbreeze 2.2 (aka PwnageTool for Windows) for creating iOS 4.2.1 custom firmware files on Windows. Just like the recently released PwnageTool for Mac, Sn0wbreeze 2.2 also incorporates the kernel based GreenPois0n exploit for untethered 4.2.1 jailbreak.

The iPhone Dev Team has just released official version of PwnageTool 4.2 which incorporates the new kernel based exploit of GreenPois0n for creating full untethered iOS 4.2.1 custom firmware files. Almost all iOS devices are supported except for iPod touch 2G.

Screenshots of the upcoming Sn0wbreeze 2.2 for Windows has been teased yet again. In case you don’t already know, Sn0wbreeze for Windows is an alternative to PwnageTool for Mac which allows you to create custom firmware files which are jailbroken, untethered, and without the upgraded baseband.

Its here finally ! Chronic Dev Team has released Windows version of GreenPois0n iOS 4.2.1 untethered jailbreak for iPhone, iPad and iPod touch. And just like the Mac version, Windows version is compatible with iPhone 4, 3GS, iPod touch 4G/3G/2G and iPad.

Chronic Dev Team has finally released the much awaited GreenPois0n RC5 which brings full untethered iOS 4.2.1 jailbreak for all iOS devices. Unlike Redsn0w 0.9.7, GreenPois0n RC5 doesn’t require you to have SHSH blobs of 4.2b3 saved on Cydia. You can jailbreak any iOS device out of the box on iOS 4.2.1 using this latest version of GreenPois0n.

The iPhone Dev-Team has successfully ported “Monte” technique back to iOS 4.1. This will enable users to untether the iOS 4.2.1 jailbreak on iPhone, iPad and iPod touch without having 4.2b3 SHSH blobs saved on Cydia.

Members of Chronic Dev Team have just released a new video which shows full untethered jailbreak for iOS 4.2.1 in action.
