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.
You can use free software like Greenpois0n, Redsn0w, and Lydia.
You can use Limera1n or WaterDropl3t. * You can use these ones, too: ------------------------------------------ * Yellowsn0w * Redsn0w * BluemeNu * Oll4 or GreenPois0n __________________________
The only way you could lock a iPod 4g or eny kind of iPod. Is to jailbreak it in redsn0w or in greenpois0n
When you jailbrake your iPod. If yo have Greenpois0n then you must use the installer it places on your iPod to manually install it. Redsn0w gives an option to auto install cydia for you.
Its called Redsn0w look it up on youtube by an author named EverythingApplePro.
redsnow works better but you need to download firmware which takes a while
Yes, now Greenpois0n can jailbreak iOS 4.2.1.
redsn0w is a program where you can hack your ipod and you can download as many applications as you want for free. To download redsn0w go to http://redsn0w.com/
No you do not put Greenpois0n on an iPod. You install Loader which in turns installs Cydia.
greenpois0n.com
hello go into youtube and search {jailbreak sherbazhashmi} and it will give u a tutorial (better then redsn0w
I know of 2 reliable jailbreaks for you to try. Both worked for me. The first is redsn0w. This usually comes out second or third, but only a few days after the first. The second is greenpois0n. This is usually one of the last to come out, and it doesn't support iOS 4.3.1 yet, but it is very simple to use.
