There is some issue with the battery getting too hot. They are giving you a free replacement. One of them I have falls into the recall. I just hope I dont get a newer version one. I hate how small the new ones are..... Here is the link..... http://www.apple.com/support/ipodnano_replacement/
I started the process, I'm just wondering what I'll get I've read around and some people say they get the new one or the original one. Time will tell. I get a package sent to me in the mail, I then send mine in and they send me something else..
I bet they will, but it could be because of the battery recall issue. Doesn't cost you anything at least! Good luck....
