I don't think CDMA is going to die with China building its network based on that technology.

Just wondering, how does this phone module function (esp. since I just ordered it). I have a CDMA phone currently and I am not familiar with SIM cards.
You stick in the SIM card, and then PCM can operatie as a phone? Is ther a built in microphone? Can PCM store phone numbers? Will it automatically mute the stereo system if an incoming call or outgoing call is made?
Sorry for the stupid questions in advance...

To my knowledge, Porsche didn't incorporate Bluetooth for three reasons:
1. the manufacturer of the PCM system doesn't offer a perfect solution
2. Bluetooth has some security flaws which could be exploited by people with "vicious minds"
3. radio waves "radiation", there are lots of passionate discussions going on right now in Europe regarding mobile phones, WLan, Bluetooth, etc. emitting radio waves at higher frequencies (900 Mhz, 1800 Mhz, 2.4 GHz and 5 GHz).
And I'm not quite sure but I think only BMW actually offers a Bluetooth option and I'm not sure if this option will have a future.
I know that CDMA is available almost everywhere in the US but the US moves towards GSM, even if they use different frequencies like 850 MHz and the more popular 1900 MHz.
Japan is actually the only other country not to use GSM.
GSM is available everywhere else in the world, including Cuba, Iraq, Iran and Syria. I think it is a great achievement for GSM to make it possible to roam almost worldwide, in my opinion CDMA is almost dead in a longterm run. 3G is the next thing (called UMTS in Germany), it is already available in lots of countries (incl. Japan) and I hope they find a standard for roaming, this would be just great.
Not to forget the 3 satellite phone systems Inmarsat, Iridium and Thuraja.
