to have cell phone companies integrate a back door in what otherwise appears to be normal circuitry. We know that telecom companies have cooperated illegally with the government on spying on Americans until they were granted "retroactive" immunity in 2008. We can't know what kind of secret deals are happening between the cell phone manufacturers and government. Any such circuitry in a cell phone is not going to be made obvious to anyone taking apart a cell phone. Jim Stone has credibility based on the vantage point of his unique skills and experience. I put this out here as something that needs to be thought about. Certainly I'd like to see more research into this but at the same time I hold that neither the government nor the cell phone manufacturers involved would be willing to prove to you how this is possible.
