If im not mistaken what I was looking for is what the "relay" would be from the SMS message .. example when you do WAP, the UP browser reports a special header .. something like HTTP_X_UP_SUBNO from the handset (this is ur mobile #) .. apparently in location based services through OpenWave there is another header which gives the location of the first tower you passed through ..

They actually list a # of methods they use in their Location Studio SDK .. pretty interesting ..

One thing Ive always wanted to do was examine the raw headers from multiple cells to see what location based (mobile station ID) info there was or might be .. has anyone experimented with anything like that in the city?

The app would need to translate the cross streets into something like
lat/long before doing location comparisons.  You'd also want your
database to have both street address and lat/long--or again, a way for
the app to derive one from the other.

It seems the smart system would be to add an SMS gateway to an internet
database.


BTW, A quick look at sourceforge for SMS utilities brings up PlaySMS:
https://sourceforge.net/projects/playsms/
and
http://playsms.sourceforge.net/web/

(Beta, but looks promising (PHP, PEAR, SQL integration, and GPL)
There's also http://kannel.org/ . It claims to be both a WAP and SMS
gateway; it requires a C Compiler.
