Supposedly you can get batteries on ebay...whether or not they are trustworthy...I got nothing. However, when my 3G finally died, I just bit the bullet and went to the Apple store to take advantage of their battery replacement program (I think it is $69). I figured they would crack it open and replace the battery. Nope...new ipod. Yep....NEW. Yeah, it was a new 3G...but still new.
