Apple has issued a new replacement program for users who own their 1st gen iPod Nano devices, stating:
“Apple has determined that, in very rare cases, the battery in the iPod nano (1st generation) may overheat and pose a safety risk. Affected iPod nanos were sold between September 2005 and December 2006,” the company wrote. “This issue has been traced to a single battery supplier that produced batteries with a manufacturing defect. While the possibility of an incident is rare, the likelihood increases as the battery ages.”
Basically meaning, you should get a replacement for your Nano now. And you can do just that by clicking the below link:
