So a family member's ipod 2g 10gb has horrible battery life, only plays around 10 songs each charge. I read about it online and decide to buy a replacement from OtherWorldComputing. It arrives and its time to install it. The problem is I can't seem to get the back cover off. Any suggestions on what I'm doing wrong? I have read many articles/watched videos/ etc, but I can't seem to get the cover off. Is there any special trick that I need to know? Thanks in advance for the help!
