Did I alread mentioned the idea to have a capacitor parallel to the battery? So the Neo1973 cold call the police even without battery and the simcard and transmitt the coordinates of the phone. ***g*** (of course with black screen...)
Well.. you could implement a virtual battery - say at 5% of the total battery charge, which could be reserved for 'emergency' type tasks. If the user chooses to explicitly override this (the option need not be obscured), then it's with the knowledge of the risks which entail. The more I think about the anti-theft ideas, the more I start to think that you can do certain things, like implement locks when the battery has been removed.. but for the serious thief, or one with access to the internet, if the battery is removable then there isn't much you can do. Now, if there was something like this guy: http://www.maxim-ic.com/getds.cfm?qv_pk=2917 Whereby, in hardware, the device would require activation for each uniquely coded battery - possible to do via USB/PC Client... then you might have the basis for an open security system, as the options boil down to: 1) Steal phone, keep battery in, no control over what the phone is doing, who it is talking to. 2) Steal phone, remove battery, unable to get over hardware lock upon reinsertion of even the same battery.. as the volitile ram holding the bootstrap code has not been filled via the USB authentication yet. Along with encrypted filesystems, this could become a very secure device, as in your handset may be stolen, but your private data can't. I don't think we can do any better, short of keeping the handset locked up in a safe.
