The first time I saw txt messaging and fund raising it was back in 2005 around the Tsunami relief efforts. I do not remember the amount of money raised or the methodology through which they raised it (direct billing or carrier collected). Recently I have been reading information on the Chronicle of Philanthropy site regarding the advances by Mobile Giving Foundation and how they worked with the United Way on their Super Bowl campaign, which raised about $10,000.
The statistics are pretty clear that the mobile device is going to be the 1st piece of computing technology for an overwhelming percentage of the population of this planet. Our friend Katrin Verclas from Mobile Active.org has really embraced this idea with their efforts to turn the mobile phone into a change agent through awareness, education and activism.
