My ipod won't jailbreak. Two days ago, it was jailbroken with no problems. I began to have some issues, so I restored it. After I restored it, it jailbroke with no problems. However, there were app organization issues, so I re-restored so that the apps would be properly organized, no alphabetized. The jailbreak worked, but then cydia and rock wouldn't download. I re-restored again and then when I tried the jailbreak, it wouldn't work. It hasn't worked since then. I'm using Blackra1n to jailbreak a 2g ipod touch running 3.1.2 software. What do I do?
