I just got my new battery which is a 330mAH for my ipod clone 1.8 2nd gen. I thought after reading a lot of topics about opening and installing batteries for ipod nano 2nd gen was easy. Once I got my battery, I try to open it but its not the same! it said it has four screws but mine doesn't. It has two screws on the bottom which I took off but the top has none and What I see when I try to take it off is its somehow connected throughout the body! when I start to take it off somehow its moving the whole board along with it and its very very stiff and I was worried if I continue to force it out something might break. Is this suppose to happen? or am I forgetting something? I am a little cautious about this.
