The Japanese government is reportedly having a chat with Apple at the moment over two incidents where iPod nanos heated up so much that they "scorched" paper.
Well now it seems the problem could affect a lot more Apple fans.
Apple has today admitted that a very small percentage of the first generation iPod nanos might have a defective battery, which could cause overheating.
In an official statement, it says: "Apple has determined that in very rare cases batteries in first generation iPod nanos sold between September 2005 and December 2006 can overheat causing failure and deformation of the iPod nano".
"Apple has received very few reports of such incidents (less than 0.001% of first generation iPod nano units), which have been traced back to a single battery supplier."
"There have been no reports of serious injuries or property damage, and no reports of incidents for any other iPod nano model."
Any first generation iPod nano customers who have experienced their battery overheating should contact AppleCare for a replacement.
"Any other customers who have concerns about their first generation iPod nano battery should also contact AppleCare."
