i am wrong or...... wheres the zip file? no link on greenposi0n for windows...tried explore, chrome, firefox and safari... did they erase the link?

golatin - February 10, 2011 at 1:46am

Worked SMOOTHLY! All apps went back to usuall after jailbreak. Thanx for all the great work!

Works perfect, remember to restore your iphone before anything. to 4.2.1 thats the best way to go on about this. dont jump from one jailbreak to another, thats most likely why most of your ipads are messed up. i love this site, it makes everything look soo simple, and it is indeed too ;-)

Oh it just worked ! Great, thanks alot.

Aboud - February 8, 2011 at 3:11pm

Didn't work for me! Got a jailbreak failed msg and then the iPad rebooted. Dont know whats wrong, I've tried many times with no luck.

Ibark - February 11, 2011 at 4:19pm

This is weird. After trying multiple times and getting JB failed msg, I use a different USB port and cable. SUCCESS!

D3mon - February 19, 2011 at 7:00am

Mine is the most wierd, i wonder i the ipad 64gb has problems, i face the same failed jailbreak and reboots itself, but it works on my iphone 4 n my ipad 16gb, so anyone can tell me whts wrong with th 64gb? I even tried using multiple computers, cables and ports, greenpsn or redsnow didn't wrk as well, even after itunes update still dont work，......

solid - February 7, 2011 at 8:37pm

Worked perfectly , I first used the tethered Redsn0w jailbreak then applied Greenposi0n Untethered jailbreak . Everything works fine . Thanks for everyone who created this jailbreak !

dilvin - February 6, 2011 at 11:14pm

Hi, hope someone can clarify. i hv jb my ipad using Redsn0w win0.9.6 and have installed a lot of apps via Installous. if i to use GreenPois0n untethered jb for 4.2.1, do i loose all those apps? thx

JEDI - February 7, 2011 at 3:32am

Tried it on my tethered jailbreak. Everything intact except Cydia crash once in a while.

blacktaurus - February 7, 2011 at 4:15pm

It worked for me, no Cydia crashes so far.

solid - February 7, 2011 at 8:35pm

I used Redsn0w win0.9.6 then used the untethered Greenposi0n jailbreak , everything works fine ^^ every app is working ...

dilvin - February 8, 2011 at 3:06am

Done! no problem so far. All intact. :) Thanks!

Your applications will not at all be affected. Talking from experience

iTool - February 6, 2011 at 1:52pm

Ok, I have an Ipad 3g, but have never used the 3g. I got it in case I went on vacations and wanted internet access beyond wifi. Question - Is the Ipad 3g even locked to a carrier? If so, will upgrading to 4.2.1 lock it back down as I am on 3.2 now.

applesinafton - February 6, 2011 at 12:15pm

Worked for me! Been waiting for months for this jailbreak! You guys rock!

Nacho - February 6, 2011 at 12:05pm

Razorbone - February 6, 2011 at 11:18am

abracadabra - February 6, 2011 at 3:46am

Razorbone - February 6, 2011 at 4:21am

Didit - February 6, 2011 at 12:21pm

Same here, Mac version works on first try

Razorbone - February 6, 2011 at 3:45am

help! doesn't work for me. tried it like 8 times now. keeps getting the "failed" message. and getting stuck at the apple boot logo. so just went back to tethered jb now with redsnow.

Paul - February 6, 2011 at 12:42pm

I just did my Ipad, was on 4.2.1 jailbroken with Redsn0w, runned Greenpois0n and worked 1st time. maybe try rebooting pc and give it another go. I'm using Win7 64bit.

Blacktaurus - February 6, 2011 at 1:10am

Worked like a charm, I ran greenpois0n on my already tethered jailbroken iPad 4.2.1. Thx

Edmund - February 6, 2011 at 9:53am

You just follow the instructions given and got it to work? Great! Anything that we need to take note of?

-kLiNe1- - February 6, 2011 at 11:16am

WOW...i also did it on my tethered ipad and it worked the first time....i thought it was gonna uninstall all of my apps and my music, but it didnt ........i guess it does its think in the background and leave all your stuff like it was ......thats Awesome.

Blacktaurus - February 7, 2011 at 4:13pm

nothing, just run greenpois0n as instructed and you will be fine...that is if you haven't done so already :-)

fireminded1 - October 15, 2010 at 4:15pm

What ive been saying is that i dont get any jailbreak failed messages. The opposite... I get through, i even se a giant limerain drop on the screen when the limera1n finishes. But in the end i dont se a loader icon or limera1n icon

Waalkman - October 12, 2010 at 10:47pm

Anyone had luck using Greenpois0n with VMWare Fusion? I am stuck in DFU mode now and can not get out. I have tried everything I know to try including restore, restore to a separate downloaded ipsw file, and forced restore. Now, the iPad is just stuck on the 'plug into itunes' screen and when I try to restore, it gets stuck at 95% and stays there. Ideas?

elko - October 14, 2010 at 5:30am

if u stuck in DFU or recovery mode use TinyUmbrella to kick it out

DGUNZ - October 14, 2010 at 5:42pm

I tried it (iPod4G) on VMware with no luck. It wouldn't show lime drop when exploiting. It also wouldn't allow me to restore until I restored my "iTunes" back to 9.2. Then I was able to restore my iPod4G. My Solution: I restored iTunes back to 9.2 from 10. Then restored my iPod4G. I bought a new but cheap Toshiba laptop, tried limera1n on it with my iPod4G and it worked 1st time around.

fireminded1 - October 12, 2010 at 6:21pm

Still no white loader app, i have rebooted and still no frickin app. I have even restored my Ipad and still its not working. I get through the whole process successfully but no cydia

DGUNZ - October 14, 2010 at 5:45pm

What iPad version software? 3.2, 3.2.1 or 3.2.2 ?

fireminded1 - October 15, 2010 at 6:38am

well, its a Ipad 3.2.2 16gig wifi model. I have now tried many times and even with limera1n and with the same results. Its says that att it has successfully jailbroken the ipad and there is now loader or limera1n icon to load cydia with. And no, it doesnt show up after a reboot and it is not on the second homescreen. I am starting to give up really

DGUNZ - October 15, 2010 at 8:56am

Re-boot your computer, download Limera1n (www.limera1n.com), install and follow instructions.

Sherifftruman - October 15, 2010 at 1:48pm

Interesting. I have a 32 gig WIFI that is doing something similar. I have tried both Greenpois0n (which worked fine on my iPhone 4) and Limera1n and both fail. Greenpois0n gets going just finem but then I get a failure message. Limera1n ends up leaving me in recovery mode and I have to use Tinyumbrella. I have rebooted the PC and made sure I have the leatest versions. This is a week old iPad.

DGUNZ - October 15, 2010 at 6:40pm

Re-install your iTunes, take iTunes 10 off and put 9.2 back on. Reboot computer then try JB again.

fireminded1 - October 18, 2010 at 6:43am

Yeesss, got it to work with the Mac version. In the first try..
