Apple Launches Worldwide Replacement Program for First-Generation iPod Nano
Apple today began notifying users of the company's first-generation iPod nano that it is now offering a replacement program intended to address concerns over overheating batteries.
Dear iPod nano owner,Under pressure from regulators, Apple agreed to provide replacements for affected units in South Korea in 2009 and in Japan in 2010. With today's announcement, it appears that the replacement program is now in effect on a worldwide basis.
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.
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 follow the process noted below to order a replacement unit, free of charge.
Customers with affected devices can fill out a claim form to confirm eligibility for replacement. Defective devices will be replaced within six weeks and will carry 90-day warranties. Customers who have personalized iPod nano devices will not be able to receive personalization on their replacement devices.
