Hey all, My ipod said it was fully charged after one hour and i pulled it out and played it on its first charge, now im hearing your supposed to wait 4 hours? Will this affect my battery life? Will i not just be able to let it run it battery and then fully charge it? This is an ipod 160GB classic by the way. Thanks. Also, my cover flow goes by artist, can I get it to go by album? Thank you.
