I just upgraded to the newest 3.0 firmware. Looks like Redsn0w 0.7.2 is the way to go. It seems pretty self explanatory and easy to use but I do have one concern. I have never put my iPod in DFU mode before, doesn't seem like a huge deal but I would still like to make sure I understand what I'm doing. All I know about it is have to hold the power and menu button simultaneously for a certain amount of time (10 seconds I think) and then release the appropriate buttons accordingly. Do I need a timer or anything? Is this a critical step that must be done absolutely right on the first time? Is there anything I need to now about Redsn0w other than keep clicking next? I'm on Windows XP Pro with the newest version of iTunes installed. Nothing else special. No lisub or anything, I have not read that I need it. I think that is for a teathered?
