From the actual bill:
"This bill would require that any advanced mobile communications device, as defined, that is sold in California on or after January 1, 2015, include a technological solution, which may consist of software, hardware, or both software and hardware, that can render inoperable the essential features of the device, as defined, when the device is not in the possession of the rightful owner. The bill would require that the technological solution be able to withstand a hard reset, as defined. The bill would prohibit the sale of an advanced mobile communications device in California without the technological solution being enabled, but would authorize the rightful owner to affirmatively elect to disable the technological solution after sale."
