เคยลองหาใน freewareppc ไหมครับ ผมลองหาดู มีที่เฉี่ยว ๆ ความต้องการบ้างเช่น
http://www.f...ebysms.shtmlFindMe by SMS will reply with an SMS that contains GPS or CellID co-ordinates and a link to website that will show the Google map with that location marked.
http://www.f...cation.shtmlGPS Location will send your location via SMS or email as Google Maps Link.
http://www.f...rescue.shtmlReliRescue enables your Windows Mobile Phone to broadcast your location to designated partners (over SMS or email).
http://www.f...rolabe.shtmlAstrolabe uses your mobile device to acquire your GPS position and send it through an SMS.
The GPS position is updated every 5 seconds (in order to conserve energy).
SMSs can be sent automatically at regular time intervals.
ผมไม่เคยใช้ เพราะไม่มี PDA
