I just came across this mGovernment solution, called CitySourced, that allows citizens to report problems and/or make suggestions to the local authorities, through their mobile phones.

From their website:

CitySourced is a real time mobile civic engagement tool. CitySourced provides a free, simple, and intuitive tool empowering citizens to identify civil issues (potholes, graffiti, trash, snow removal, etc.) and report them to city hall for quick resolution; an opportunity for government to use technology to save money and improve accountability to those they govern; and a positive, collaborative platform for real action. Our platform is called CitySourced, as it empowers everyday citizens to use their smart phones to make their cities a better place.

Obviously, this is not a direct mobile marketing tool, but the potential for these types of applications is, I believe, obvious.

There's a pretty cool video presentation there as well, which is I guess the best way for you to really see what it's about:




Do note that it's worth seeing the video till the end, if this interests you, as there are some pretty interesting comments and suggestions to hear.
