Will the SIM cards fit in an iphone 4 which requires a micro-sim?

At the moment the 004 SIMs are a standard size. The only micro-sim we provide is with the French pay-monthly iphone tariff, but we anticipate them to become more widespread in the future. The global SIM is also a standard sized SIM. SIM cards can be cut to size to fit as a micro-SIM but we do not recommend this as it renders any guarantees void.
