I have a 3rg gen 32 gb ipt. I have the shsh blobs for 3.1.3 through now. I want to jailbreak. I have several questions: There isn't a way for me to get the 3.1.2 blobs so I can jailbreak with the new one is there? Where does iTunes save backups of my iPod touch, so that I can back up the backup? If I downgrade to 4.0, can I use a backup from 4.1?
