20 - 40 minutos
My iPod was only playing in mono. I tried several sets of headphones, tried cleaning the jack, then found iFixit.
This is the first time I've ever tried to fix anything electronic, so it was pretty daunting at first. The step-by-step instructions and photos were really helpful. I had some trouble getting the iPod open, because I was being too careful, I think. I finally got it open after I got mad and twisted the opening tools a little. Everything else was smooth sailing. It took me about 30 minutes just to get the thing open, and then another 20-30 minutes to complete everything and put it back together.
I would get an extra set of the opening tools, because by the time I got the iPod open, both my sets were broken. Also, when it says to "wiggle" the tools, you should actually twist them slightly, to about a 30-45 degree angle. It helps to leave one tools wedged in while working on the next side of the iPod.
Finally, those screws are SUPER tiny. Be very careful about picking them up, moving them, etc., because if you drop one you will never ever find it again.
