Symptoms - iPod freezing and needing resetting. At times a song will start - stop -start up a dozen times - the next song will be fine - going back to original song will be fine. All songs play fine through iTunes on Mac. Replaced battery last summer - when it was warm. Temperature when I am running with iPod now is around 25 F. Is it the cold weather? Anything I can do? I have a second generation 10 gig model. Would a nano be better? Allan Nashua, New Hampshire www.nebirds.com
