Starting Nov. 1, T-Mobile will offer the iPhone exclusively in Germany (with a T-Mobile contract) for approximately 450 euros (roughly $612), Reuters reports.
Also according to Reuters, Vodafone Group in Britain, Telecom in France and Telefonica in Spain have the leg up for partnering with Apple in their respective countries.
