bought my girlfriend a first gen white 1gb nano 2 years ago for christmas. since then, i have replaced it with a 4gb green nano since then (i guess considered 3rd gen?) she gave her first gen 1gb white nano to her dad...he says he only gets about an hour out of it before it shuts off. he's doing all the right things to conserve battery life, like no backlight, not changing songs often, no EQ, etc. i'm not sure what to do with it, it would be $66 to have apple replace the battery. on ebay, i'd probably only get maybe $20 for the nano... what to do ? were the nanos ever recalled for a battery problem?
