While Apple may have moved on to selling the 4th generation iPod nano, consumer protection agencies are still focused on gen-1. For good reason too, apparently, as there's mounting evidence that those early white and black plastic players have a tendency to overheat, swell, and possibly burst into a nasty chemical fire. Responding to four formal consumer complaints made between December and June, the Korean Agency for Technology and Standards sent a request to Apple on June 25th recommending that Apple "aggressively" collects first generation iPod nano with Lithium Ion batteries made by the Chinese company ATL. Initially, Apple agreed to replace faulty units as they did in Japan upon request by the consumer. However, KATS is now reporting that Apple will recall the players under its own initiative making this the first formal iPod nano recall we can, uh, recall.
