My question is: If you buy an application that (say) $ 10. 1999, you pay only once, or not a monthly fee? It may be a stupid question but I do not know now than later when I receive an invoice for my credit card. This question is for the owners or their representatives. Please post if you have an iTouch or iPhone. If you are the owner or representative of your answer, does not mean anything to me. Apple iTouch 18GB 16GB Generation 3 is just kidding:]
