Reset AppStore account in iOS5 Simulator?

Question

iOS

As you know (or don't know), the iOS5 Simulator introduced StoreKit support . That's great, now you can debug In-App Purchases in the simulator. However, once you make a purchase, the login is remembered and cannot be changed. Naturally, there is no “Shop” item in the settings, so you cannot “Log out” from this account. Removing the application from the simulator did nothing, as well as restarting the simulator. Deleting a test account in iTunesConnect - too.
Any ideas?
