My iPod touch has been giving me alot of trouble lately (turning itself off, many errors), and I want to trade it in under warranty for a new one very soon. However, I know that Apple will be releasing a new iPod touch around September 7-9. I purchased mine on September 23, 2009. If I brought it into Best Buy on the 22nd or 23rd of September this year, do you think that I could possibly get a 4th Gen back? Do you think they will have already gotten rid of the 3rd Gens already? I must know what you guys think before I try it.
