iPhone 5 confirmed to use nano-SIM, current SIMs not compatible

Apple did not mention that iPhone 5 would use the recently approved (and Apple-designed) nano-SIM standard. Apple is relying on that even tinier subscriber module for GSM, HSPA and LTE networks. Unfortunately it is not possible to create nano-SIM out of micro-SIM. Cutting does not help, they are just not compartible.
