Well previously, when I hadn't known of iPTF, I had tried to restore my iPod. The first time, my iPod was acting weird, so I restored it. It went through the deleting process and everything but wouldn't load up again. It would just stay black. The Apple rep couldn't help and I had to get a new one (warranty). A second time, I tried upgrading to 3.1.3. Same thing happened. Now i'm considering upgrading to 4.0, but I really don't want to the same thing to happen. With the new iPod, I've tried new wires and I've also tried different USB ports. What can I do to avoid this? Should I just got to a friend's house and do it? For reference, I have an MC model 8 GB iPod Touch 3G. I'm considering upgrading coz of that tutorial that lets me enable multitasking.
