Posted by on Feb 05, 2011 | Leave a Comment

After remarkable release by the Chronic Dev Team i.e. Untethered iOS 4.2.1 Jailbreak at, the website is in outage due to heavy traffic of downloading. The newest Untethered Jailbreak is Windows, Mac and PC based tool that jailbreaks all new generation iOS 4.2.1 supported devices.

The team of the Chronic Dev launched GreenPois0n RC5 recently. Actually GreenPois0n RC5 is an untethered jailbreak for iOS 4.2.1 devices including iPhone 3GS, iPhone 4, Ipod touch 2G, 3G, 4G, and iPad without using ‘4.2b3’ SHSH blobs in Cydia.

At, the jailbreak tool is available for the Mac OS X platform and will be offered for Windows version very soon. The iOS 4.2.1 running device users can download Untethered Jailbreak from the website, but currently the website is not operating because of heavy traffic. When you browse the website, you will get timed out connection of this website.

From the Chronic Dev Team, Joshua Hill (also known as p0sixninja) tweeted, “The exploit is already patched in iOS 4.3 so were trying to get it out ASAP.” For Mac OS X, Greenpois0n tool allows untethered jailbreak, so users will not get jailbreak for device every time, users need to restart it. To carry out clean iOS 4.2.1 restore, connect your device to Mac using USB and then jailbreak it. When you jailbroken it, the users will find Cydia installed in their iOS device. Thus users will not require following ‘Just tethered boot right now’ option for any further extent.

Jailbreaks can be easily downloaded for your device by just following little process. From the all iOS 4.2.1 running device, the iPhone 4 users have to evade from the latest iOS Jailbreaking because it is just for those who want to unlock their device because this jailbreak updates the device’s baseband firmware, so users can not use any custom micro SIM.

Right now, the people are facing trouble for downloading Greenpois0n Untethered iOS 4.2.1 Jailbreak from its official website. So you may need to wait for that.

Joshua Hill (p0sixninja) said on tweeter, “Sorry if server is down, 500,000 hits in one night is too crazy!!
