This is not an easy thing to do. I just happened to be surfing the web for information about my nokia. Low and behold I came across a site devoted to hacking the phone. It had plans for cables and the basics of the communication protocol. The point I am trying to make is that you will need to surf the web for information about setting up communication to your phone. Each phone is different and each manufacturer can use whatever protocol they want. Once you have than info, we can then give you advice about implementing it in LabVIEW.
