I opened iTunes the other day and connected my first gen iPod Nano. Then this window popped up and told me to download and install firmware version 1.3. With the update it said something about Nike+ voice track overlays were supported. A quick search on the web gave me nothing. Then today I connected my battery drained iPod to the computer and instead of giving the old black battery icon with the slash through it, it gave me this new message. Pretty interesting if you ask me. Has anyone else noticed this or gotten an update for their iPod?
