Bought Cro-Mag when the App Store became active. Noticed on my iPod Touch that an update was available, but update didn't show up in iTunes. Downloaded and installed via iPod. Did not notice a screen saying I would be charged. But, I was. It just showed up on my credit card statement. It's not a huge amount of cash, granted, but doesn't exactly instill a lot of confidence in the App Store. Now wondering if I missed a screen saying I would be charged, but why would it if the app was already installed and I clearly remember tapping an 'update' button.
