Apple has agreed to a recall of first-generation iPod nanos in South Korea, according to the Wall Street Journal. The company was asked to perform the recall in a June 25th motion by the Korean Agency for Technology and Standards, as a result of a number of complaints about batteries overheating or even exploding. "Although the overheating problem doesn't affect the batteries that are being used now in iPod nanos," Apple says in a KATS statement, "concerned customers can get a replacement battery."

Problems with first-generation Nano batteries emerged in Japan, where several incidents occurred in 2008 that not only destroyed players but caused injury, also threatening damage to surrounding objects and furniture. Apple has generally agreed to replace at-risk batteries through AppleCare, but the policy has not been given much publicity outside of media reports. In March, a lawsuit was filed over an exploding iPod touch.
