I'd like to share my experience. I have been working in the Sandbox and the app receipt missing after deleting the app. (And then re-Command-R-ing) I do not know if this happens in production, but it sounds as though it does. Asking for a refresh upon the first ever app boot, and prompting the user for their password is startling. This is an issue, of course.

It seems as though [[SKPaymentQueue defaultQueue] restoreCompletedTransactions] also silently refreshes the app receipt without popping a dialog box. Meaning, after transaction have been restored, asking for the appReceiptURL + Data returns a non-nil value. This is just from my short amount of testing. Please, do your own testing.
