Hi. Got a newly released MBP recently. Now I'm looking at ipod touch as well. I purchased a used touch on ebay a few days ago. I feel I got a very nice price. I plan to probably resell it later in the year. Then get a new generation touch after they are released. I'm a little confused on how many generations of touch's have been released so far. I feel like their have only been 2 generations. Though ebay shows used touch's for sale as both 2nd and 3rd generation listings. The one I purchased on ebay was listed as 2nd generation. Could someone clarify my generation confusion please. Knowing that I am receiving the 2nd generation soon. Will this 2nd I'm waiting for to be delivered support multi tasking if I upgrade to 4.0 ? My purchase is being delivered to me with 3.1 installed.
