want to make GPS tracker using Arduino and Sim808

hi all,
i am new one with Arduino . i want to make GPS tracker that can send Latitude and Longitude om my mobile in the form of message. i have done it by simply using switch button, but the thing is that, same thing i want to do when i make call on sim808 module. for switch button i have used "Softwareserial.h" library and call status i am going to use "GSM.h" library .
so my question is can i used both library "Softwarelibrary.h" and "GSM.h" in sketch . if yes what change should have to do.
please help me waiting for reply
thanks in advance

so my question is can i used both library "Softwarelibrary.h" and "GSM.h" in sketch .

You can not use SoftwareSerial and GSM in the same sketch, because the GSM library re-implements SoftwareSerial, instead of using the existing version.

Not that it really matters, since the GSM library is ONLY for the official GSM shields.
