Yes, now Greenpois0n can jailbreak iOS 4.2.1.
There are many ways but what my friend did was download Greenpois0n software on a pc, then open it up in dowloads and follow the instructions that come up
No you do not put Greenpois0n on an iPod. You install Loader which in turns installs Cydia.
greenpois0n is the best jailbreaker for ios 4.1 on windows that i have used( i have personally used it and it is safe , just beware of fake downloads)
No
Yes, GreenPosi0n is a free jailbreak for iPhone, iPad, and iPod Touch. You can find the link to GreenPois0n's offical site in 'Related Links' below.
This is the easiest thing in the world... 1. you go to this link http://greenpois0n.com/ (also make sure you have winrar) 2. when you do this go to the top right corner of greenpois0n and click on downloads 3. then find which IOS firmware you have DO NOT click on the firmware, right below it, it will show you what you have windows xp, vista, or mac just click the download button next to the one you have. 4. when the download is done you will have a download with three books stacked on top of each other, right click it and go to extract files 5. when that is done click on the folder and open greenpois0n 6.plug your ipod touch into the computer DO NOT put it into DFU mode yet FIRST turn it off then click on the prepare to jailbreak 7. follow the instructions on putting it into DFU mode 8.when your ipod is put into DFU mode keep holding the home button until it says jailbreak complete on greenpois0n then you can let go. 9. after that you will go to your homescreen on your ipod and on your next page there should be loader 10. click on loader and download cydia, then restart if it tells you to do so or it might do it by its self. thats it your ipod will be jailbroken please tell me if this worked if not i will show you more ways to jailbreak your ipod :) but it wont be with greenpois0n.
It already is for a long time
Of course...by restoring the ipod.
it has but not for the iphone 4
It is a matter of opinion, in my opinion Greenpois0n is better because that is what i used to jailbrake my ipod touch 2nd generation 4.2.1 ... do NOT use jailbrakeme.com that is just a virus and it brakes your ipod.
Yes. I recommend the greenpois0n jailbreak, at greenpois0n.com
