It's definitely also a good argument to just use what's in hand! It is actually also possible to connect to the internet using that module, using good old GPRS (The module contains a full TCP/IP) stack. Of course not near as fast as an average wifi connection. I used it to create a set-up where you can send a text message to the module: "Where are you?", it would then respond with the latitude and longitude as well as the geocoded address using Google Map's Geocoding API over GPRS.
