I want to know what apps I've paid money for, as opposed to free apps that were downloaded.
I need to know this because I gave my little brother my old 3GS to use as an iPod which remains attached to my iTunes account because he doesn't have a credit card or an income in order set up an account. I notice that he downloads a lot of apps, games in particular, and I'm worried because I've tried a few that seem like they could easily charge for. I often download apps that I pay for, so often that I wouldn't know if he was buying things without my knowledge.
Every now and then I notice a charge from iTunes that I don't remember making, so I need to know what I've paid for. Is there a way to show what apps I've actually spent money on?
