Do you own a first-generation iPod nano bought between September 2005 and December 2006? If you answered 'yes' then you could be eligible for a free replacement thanks to a manufacturing defect that could result in the diminutive music player overheating.
Apple is recommending that owners stop using their iPod nano and check to see if they are eligible for a replacement unit, free of charge. Not all first-generation iPod nano units are affected - entering your serial number here will tell you if your device is affected.
Note: Only units with a black or white plastic front and a silver metal back are affected. Later iPod nano models with a metal front and back are not affected.
If your iPod nano is affected, you will be instructed to send it back to Apple. You will receive your replacement unit within 6 weeks.
This is a great opportunity to get that old iPod nano that's languishing in a drawer for a few years refreshed.
