How could they track the software sales? They're from digital distribution, vgchartz can't track software sales for the iphone for the same reason it doesn't track steam sales.
Just looking at some sales. In q4 2008 apple sold "6,892,000 iPhones" http://www.appleinsider.com/articles/08/10/21/notes_of_interest_for_apples_q4_2008_results_call.htm The article also states that they've sold over 10 million iphones this year. So its hardware sales are impressive, not that that translates into impressive software sales neccesarily as it isn't a device thats just for playing games.
