Sorry if this is old, and if not, sorry for minimum details. Look at App #14 in the US Top Grossing apps; there is some random app (in Mandarin) that costs $119.99. I've never seen this app before, nor have I heard of it. The reviews specifically complain about being charged for the app which they didn't buy. Looks like a very simple news reading and/or RSS program. It looks like this hasn't been a widespread problem yet. The app is from "iQian Studio", and was released on April 30.
