To get all these information from one site is very difficult and what is annoying is that they hardly go straight to the point. So if you have enough time search the above websites but if u are impatient as i was then spend some money to get exactly what u want in the shortest time possible.
I was suprise to meat this guy from africa in a forum he ask me to chip in some cash which i did to my greatest suprise he gave me exactly what i wanted. a very simple circuit diagram with very few components on how to connect the pic to the phone, a source code and and a list of AT commands supported by the phone. I am not saying that you should trust him but if you want to try the this the email
