I've been trying to use blackra1n to jailbreak my iPod (2G, 8GB, 3.1.2). I plug it in, press the button, and the picture comes up on my iPod's screen, it reboots, but after that all I get is the 'Connect to iTunes' screen. I've tried using blackra1n about 5 times now, it hasn't worked at all. Am I doing something wrong? Or is this a known bug?
