When, if ever, will it be possible to preorder the iPod touch 4th generation on AMAZON? I know nobody knows for sure, but when were the past iPods put on Amazon for preorder? EDIT: I specifically wish to buy from Amazon, which is why I placed it in caps. Not only do I have Amazon gift cards to burn, but I really appreciate their excellent customer service. Even if it takes a little longer, I'd prefer to buy from them than Apple or an electronics store like BestBuy.
