untethered ios 4.2.1 jailbreak

The video confirms an iPhone 4 running iOS 4.2.1 firmware which is jailbroken (untethered) using Greenpois0n. It will not require iOS 4.2b3 SHSH blobs, as previously said by posixninja. Greenpois0n release seems imminent.

Pod2g: “A small bug remains, the wifi icon don’t show up. But it’s there. As you see, we need some more time to fix and pack everything.”

The untethered iOS 4.2.1 firmware jailbreak will be out soon!. We’ll keep you posted as soon as Greenpois0n jailbreak is out! Stay Tuned!

Chronic Dev-team should have more concentrate unlock new baseband rather than waste time on jailbreak new firmware!

treoluv January 22, 2011, 10:56 pm


Now, tell me how can you unlock it without jailbreak it first? Furthermore, can you help them to have “more concentrate unlock new baseband” by donate some money?!

Jim January 22, 2011, 10:42 am

Geohotz has enought trouble with law suite lately, as a result I don’t think there will be any update for jailbreak or unlock in near future.

Ryanu January 22, 2011, 1:05 pm

Jim u are wrong..apart from geohot..there are lots of devs working on jb or unlock..sherif hashim is working on unlock..I think they will release it as soon as iOS 4.3 goes public..my 2 cents

treoluv January 22, 2011, 11:00 pm

Yeah, I believe you when I download it. 🙂

great news guys!!!
YR work is really appreciated…

athynz January 23, 2011, 9:51 pm

I can’t wait… went from an iPhone 3G jailbroken to a new iPhone 4 already running 4.2.1… Stock OS is good but jailbroken would much, much better! Hope there is a Windows version out soon – tired of waiting on redsn0w to deliver a windows untethered JB.

Daniel January 27, 2011, 9:40 am

I know it takes a lot of effort,and I really appreciate it….but all this jailbreak/unlock thing is a bit ridiculous.We are gonna be waiting for the new jailbreak while Apple releases the iPhone 5.

Hi, iPhoneheat

Does this only Jailbreak? What about unlocking the iphone? I have a iPhone 3GS 4.2 I used redsnow to jailbreak & unlock but it’s tethered meaning I can’t turn off my iphone. I’m just hoping that this can unlock it so that I can turn my iphone on and off.

Thanks thesaipankid

iPhoneHeat January 27, 2011, 3:52 pm

Unlock is done with a separate tool.. for iOs 4.2.1 there’s no unlock out yet!

thesaipankid January 29, 2011, 11:04 am

Hi, iPhoneheat

Just wondering when will this be out?


thesaipankid January 29, 2011, 11:05 am

iPhoneHeat January 29, 2011, 11:00 pm

thesaipankid January 30, 2011, 5:21 am

Hi, iPhoneheat

I have a question about greenpois0n 4.2.1 jailbreak. Can we use this to jailbreak iPhone 3GS 4.2.1 on Modem Firmware 06.15.00 and still use repo666.ultrasn0w to unlock it?


stealingsociety666 February 4, 2011, 11:13 am
