Of course...by restoring the ipod.
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 Greenpois0n...connect ipod and run the program, then follow instructions
No, you can't delete them but you can check out how to put FULL movies on an iPod...and then tell me becus I have no f**king clue HOW!
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.
The only way you could lock a iPod 4g or eny kind of iPod. Is to jailbreak it in redsn0w or in greenpois0n
Yes. I recommend the greenpois0n jailbreak, at greenpois0n.com
delete the one on your ipod then drag the one from your library back to your ipod
With limera1n or greenpois0n 4.1 firmware I suggest limera1n
You Can't But You can put the songs on your ipod onto itunes then put them delete them And then sync ipod with itunes. then you will get them back and you will get then new ones to. i hope that answers your question.
No, updating an iPod will not delete anything on your iPod.
You can use free software like Greenpois0n, Redsn0w, and Lydia.
