Since " it worked was at the apple centre and my brother's computer." and you revealed nothing about the machines that had issues, how can we begin?
there's something really wrong going on with my ipod. everytime i plug it into my computer, not only isn't it read by the computer, it disconnects the internet as well! I tried it again on my sister's computer, and it shut down her computer as soon as i plug it in!
the only place it worked was at the apple centre and my brother's computer. please help! i've tried restarting it but it still doesnt work!
