I am not well versed in older iPods so sorry if this is an elementary subject. A co-worker is selling her iPod and I dont know what generation it is. Here is the description. -4GB -Black and white screen -Silver in color -dock connector -headphone port has that extra port right next to it -its all kind of fat. Almost twice as thick as my 5g video. I think its a mini, but not sure what generation it is. Any thoughts? I could take a photo of it and upload later if needed.
