I’ve noticed a few reports recently, where a previously paid-for app or game becomes free, with in-app purchases to get back old functionality. People that previously paid, are now in a position where they have to pay again, to get the same function. If this happens to you, definitely try contacting Apple for a refund (instructions).
Officially, Apple don’t do refunds for anything purchased from iTunes or the App store, but I’ve had a couple of naff apps refunded in the past.
