<font size=2 face="sans-serif">Hello Nikolaus,</font>
<br>
<br><font size=2 face="sans-serif">> I do not get what the allusion
to the iPhone helps,</font>
<br>
<br><font size=2 face="sans-serif">I just wanted to remind the fact that
the iPhone collects GPS data. Nobody knows why and after discovery Apple
claimed it to be a bug. But we all know how greedy big companies are.</font>
<br>
<br><font size=2 face="sans-serif">> What are the requirements that
it works?</font>
<br><font size=2 face="sans-serif">></font>
<br><font size=2 face="sans-serif">> technically:</font>
<br><font size=2 face="sans-serif">> * there must be an antenna connected
to the GPS receiver (it isn't).</font>
<br><font size=2 face="sans-serif">> * ...</font>
<br>
<br><font size=2 face="sans-serif">IIRC it was planned for further versions
of the GTA04 to use the modem's GPS in order to save the extra chip.</font>
<br>
<br><font size=2 face="sans-serif">> * the UMTS transmitter must start
transmitting without user interaction and this can be detected easily.</font>
<br>
<br><font size=2 face="sans-serif">Really? How will you distinct between
good and bad data within transmissions? Mobiles constantly give some ACKs
to the base station in order to tell them that tey're still active. Will
you really be able to detect some extra bytes or even data records without
huge effort?</font>
<br>
<br><font size=2 face="sans-serif">> * OPTION must have taken over a
very high risk to implement such a feature and to try to hide it from the
public</font>
<br>
<br><font size=2 face="sans-serif">Not higher than Apple did.</font>
<br>
<br><font size=2 face="sans-serif">> (what do you think would happen
to their reputation if such a feature would exist and become public?)</font>
<br>
<br><font size=2 face="sans-serif">Nothing. Apple claimed it to be a bug
and millions of users didn't cry very much. How many users does OPTION
has?</font>
<br>
<br><font size=2 face="sans-serif">> So I don't believe that it is a
relevant scenario to think about, because locating someone by IMEI is much
easier and better to hide.</font>
<br>
<br><font size=2 face="sans-serif">That's right. But it was only the one
scenario that I choosed because thanks to Apple it has already been proved
to be realistic. I don't want to stress this list with other scenarios
that easily could be called to be paranoid. But be sure I could imagine
some.</font>
