Clone Brick Phone?
Posts: n/a can someone please help me clone my brick phone? I would like to have my cell # in my van on my brick phone and use a small phone for everyday use. I would also like to buy a small phone too... package deal? My phone is an 'ultraclassic' brick phone. I used to have it cloned a long time ago but lost the 'cloned' phone. thanks Michael Cameron  Responses to "Clone Brick Phone?"

Posts: n/a Re: Clone Brick Phone? If I only use one phone at a time who cares? It's my phone #...how can they 'detect' that? I pay enough for my phone bill and would like some convinience and ability to use a phone that actually has good reception sometimes (brick phone!) unlike all these junk small phones. Anyways, does anyone have any ideas?

Leaving that detail aside, from a technical perspective, one way they can detect clones is via "RF fingerprinting". This is where they analyze the waveform of the signal generated by the transmitter on the phone; apparently there are idiosyncrasies in each individual device in how the signal looks when it is being turned on and off, and in how the modulation is done, due to slight differences in the components. Another technique is the A-Key: all but the very oldest analog phones have something called an A-Key (Authentication Key) where the system can do a cryptographic challenge to the phone.
