Apple is recalling the first generation of iPod Nano, launched way back in 2005, citing a risk of battery overheating. The Cupertino-based company says that the fault lies with a single supplier that produced batteries with a manufacturing defect. Although the risk is low, the company says it will be more significant as the battery ages, and the affected products are five to six years old now. "While the possibility of an incident is rare, the likelihood increases as the battery ages," the company says Apple advises Nano owners to stop using theirs, and will offer replacement units for free. The new units will be under warranty for 90 days. If you happen to own one of the affected Nanos, and you're in the U.S., Europe, Australia, or Japan, you can order your replacement unit online here. Note though that only units with this defect are eligible for the recall program. Photo: Carl Berkeley
