Florian Mueller in an uncommon leak Monday morning has understood that Apple is promising to offer its proposed nano-SIM standard royalty-free. In a letter originally sent to ETSI on March 19, a senior attorney at Apple understood that the company had "caused some concern" among competitors over its owning the patents and would give free licenses in return. As expected, the condition was that the nano-SIM become the defining standard and that others agree with a view to doing the same.
