I've purchased the UK full postcode update for Navigon UK and recently JB'd my 3GS. Now when trying to re-activate the in app purchase after a re-install and JB, It references "Sandbox" when I enter my password. Then fails with - This is not a test User account. Please create a new account in the Sandbox environment. [Environment: Sandbox] Cannot connect to iTunes Store. Are in App purchases borked with BlackRa1n JB's?
