- no, the "firewall" proposed on cryptophone is not feasible
. Yes it is possible to hijack a phone connection
- Yes, that includes the GPRS data
- Not so sure about this one, but I feel confident,that once you have hijacked the phones GSM/GPRS you can gain enough control to activate the camera and microphone etc by several types of attack. Possibly you can do this by a specially crafted SMS, but definately I have no doubt you can do this if you hijack the phone GPRS connection.
. Why not ? The celltowers connecting the phone can be maches at the simplest by a comparison to know cell tower ID ranges or specific IDs? I think thi could be quite easily implemented.
