Zanny, I disagree with your use of the "nothing is completely secure" truism as an argument against "storing private keys inside cellphones is not a good idea".

Zanny, I disagree with your use of the "nothing is completely secure" truism as an argument against "storing private keys inside cellphones is not a good idea". The local police department has ISMI catchers. I estimate they won't have the ability to extract a file via the baseband until something like eZing becomes ubiquitous. At that point, automated private key extraction will just become another feature of the ISMI catchers. All of this is tangential to the real problem: basebands. Both in cell phones and cable modems. Time to take 'em back. You wouldn't allow OTA updates of your router or PC... Now would you? I'll anticipate one response: "But, giving consumers control of their PHYs would be hell for the cellular/cable operators!" Well, after a few years, their/our networks (and devices) will be more secure.
