GSM module interface for arduino

[bobdxcool]

Hi guys.

I wanted to send some information from arduino to a mobile phone after comparing data acquired from google maps and GPS . IS it better to use gprs or gsm?

Could you please suggest a circuit??

What is this GPS/GPRS shield?? Can it be used to get gps data and send it to a mobile phone??


Also, what is the method of getting data from google maps to arduino board???
