How do you identify the different generations of Ipods? What I understand is that the latest is Generation 5.5. Is there a 5.0? How do you tell the difference. I have an unopened Ipod that is model "MA450LL/A Ipod 80GB Black". I see no generation information on the package. Do you go by serial # to tell generation? This has Johny Depp on the front and "Dani California, Red Hot Chili Peppers, Stadium Arcadium" on the back. And why are people selling what they call 6th generation Ipods on Ebay which are being bid up to over $400? This one is selling at $385 with time to go and it is called 6th generation. Ebay #110118635978 Apple's price is $349 I believe for the latest model which they say is 5.5. Why are people paying more on Ebay for the latest model? Like this one (150115747555) at $385 Buy it now which says MSRP is $599 and says it is being sold on the Internet for $449 or $100 over Apple's price. Confused, is the 6th gen out already in Hong Kong and China? Could there be 6th gen on US streets before Apple announces it? How would you identify it if it was?
