Picture of How to jailbreak ipod touch with firmware 4.2.1 or lower
This is my first instructable on how to jailbreak an ipod touch with firmware 4.2.1 or lower.  Jailbreaking you ipod gives you many opportunities for free stuff like music and videos, you have a theme on your ipod and so much more.  A lot of people may think it takes a genius to jailbreak an ipod touch but I'm 15 and i have jailbroken 4 out of 4 i have tried to.  also it is an un-tethered jailbreak and it doesnt work for 2nd gen ipod touches that are mc models.  you can find out the model the same place the firmware is.

Step 1: Check your firmware

Had troubles the first time putting my iPod Touch 2nd Gen into DFU mode. So I had to redo those steps, and when I did the Green Poison window didn't recognize that it was in DFU mode. So I had to restart that portion but I tried it again and the window recognized that it was in DFU mode and it started to do it's work. It Jailbroke it, the screen on my iPod came up with all the white text as if it were a CMD and once that finished my iPod restarted itself. I went to the Loader icon and once Cydia was done downloading I believe it restarted the iPod again, loaded up Cydia, waited for that and bam! Successful Jailbreak within an hour or two. Confusing as first, you're not alone out there people, but I understand now. Thanks!!!
OMG I just jail breaked Ipod touch 2nd G and now it doesn't open! What to do? Help please

mrfrenchy2 years ago
I have been trying to jailbreak my ipod touch. I follow the instructions as it tells me to do, but it wont jailbreak. I have tried time and time again but everytime I hold the home button and sleep button and do what it tells me after it's finished it asks me to try again and when I look for the loader app it's not there. I am doing it right by the instructions but it won't jailbreak. What is the problem???? Please help, I really want to get this thing jailbroken.
