I've updated German officially unlocked, contract-free iPhone to 1.1.3 and iTunes thought it would be a good idea to brick it. I have one of those "simlock frei" officially unlocked German iPhones. I've spoken to Apple technical support and they haven't told me whether this is a problem specific to unlocked German iPhones but they said that "many people" had their iPhone bricked with the 1.1.3 update. They told me they can't help me right now. Cupertino has told them to wait until they come up with a solution.
