I want to develop a mobile phone application that helps a person (say A) to know the location of another person(say B). The basic idea is to obtain the cell tower id from B's phone and forward it to A. The application in B's phone has to run continuously in the background and whenever the cell tower id changes, a sms with the new cell tower id has to be sent to A's phone.
I initially started working with j2me on my nokia 5800 phone. Only later did i realize that it is not possible to send sms without user intervention, unless the application is signed by a trusted CA. I am working on this for my FYP and i cant afford to go down this road.
I learnt that one can obtain the cell tower id in Symbian C++ using CTelephony. I went through forums that suggested that it is possible to send sms without user intervention in Symbian C++ using RSendAs. Is that right?
Can one send the cell tower id, every time it changes, to a pc also without user intervention?
Before i start working using SymbianC++, i would like to know if any of the above requires getting the application signed for it to work. I have already lost precious time. Please help.
Thanks in advance
