I disagree with the “theory” here. You don’t have to bend the case at all. Watch the x-acto blade video on youtube (it’s linked above in the Step 4 comments). The idea is to slide whatever wide flat tool (putty knife, x-acto blade, iFixit Jimmy, etc…) in between the clip and the body. Setting the iPod flat on the table instead of holding it will help and you won’t cut yourself if a tool slips out. As you disengage clips, you will find that the body will start coming out on it’s own without having to flex your wide tool and bending the case in the process.
