Hi, I need some serious help regarding jailbreaking of IPOD touch 4G. I have some queries regarding this: 1) Yesterday, I was googling to find jailbreaking software and I came to knoe about greenpoison. I tried using it to jailbreak but I dint succeed. Now, is there any other recommended software to jailbreak the IPOD? Or should I use greenpoison only? Any guide to use the greenpoison? I watched a couple of videos in youtube but they are not using greenpoison. 2) Does jailbreaking void warranty? 3) If anything goes wrong, can the previous state be restored? 4) Do I need to take a full back up of my current IPOD touch? If yes, then please recommend some software to take the back up. Thanks in advance. --- Updated Post - Automerged --- Due to session time out, my new thread got posted twice, hence, I request mods to delete the other thread. --- Updated Post - Automerged --- Guyz no suggestions?
