I downloaded a App from Apple into my Mac, and then sync'ed my iPod Touch. After playing with the app awhile, I decided to rate it online. Only that Apple's site pops up a dialog box claiming I don't own it. Sure I do: it's on my iPod. I am using it. If I delete the app, then another dialog pops up, this time on the iPod, asking that I rate it. Back to the App store to see what gives. No ability to rate. I click Get App. Now a dialog pops saying I already purchased it. But I didn't: Apple said so when I tried to rate it. Back to the page to rate it. NOW it gets it right, and my rating is accepted.
