Apple calls back the first generation iPod nano because of possible overheat risk.
Apple announced a replacement program for the iPod nano 1st Generation released between September 2005 and December 2006. Apple has determined that, in very rare cases, the battery in the iPod nano (1st generation) may overheat and pose a safety risk. Damn, I still own one of these, but since I own an iPhone I am not using it any more.
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.
Apple recommends that you stop using your iPod nano (1st gen) and order a replacement unit, free of charge. Get your new iPod nano 1G here.
