O vídeo abaixo mostra o problema (não é o meu - mas é o mesmo problema);
Se alguém souber como reparar, me avise!
One year using my iPod Nano 6G, and today the main power/hold button went down, and didn't come back. The metal button itself moves, which indicates something inside is stuck. Whatever - the device is useless now.
The video below shows the problem. It's not my video, but it's the same problem.
If anyone knows how to repair this, please tell me!
