I'm curious if anyone knows what happens when you attempt to redeem a promo code from the iPhone and the application fails to download because it is big enough to require a Wi-Fi connection? I know that when I went to iTunes to attempt to get it there, the code shows as already being used. I also tried to bring up the option to write a review, but I was told I needed to own the application before I could write a review. It seems I don't have credit for it, at least so far. I'm betting I'm not the only one to have had this happen. I'd be interested to know whether the promo code is simply lost.
