This is only for the Nano 1st Generation-The Plastic One.
Apple has decided that this model may catch on Fire Somehow and is offering a replacement program though they are more than 6 Years old.
If you have one of these just Google the subject and you will be able to enter your serial number to see if it is one that is covered.
They will send you a box to ship it back in.
In a few weeks you will receive another one .
The sweetness is that they evidently do not have enough of the old ones to replace it with so Yesterday I received a current 6th Generation Nano instead!
This seems like another Genius idea from Apple to me as I will certainly tell all about the great service and Perks and clearly am even more endeared to Apple than before,if you can imagine it.
So dig those old iPods out and have fun!
