Monsters and Commerce wrote about how 700,000 mobile phone users in Hong Kong have signed up for a "do not spam" mobile phone registrar. That's definitely an interesting idea, because it's seemed to work pretty well here in the United States.
"Since then 3,064 people in the city of 6.9 million have registered complaints with the Office of Telecommunications Authority about unsolicited calls. Of those, 2,091 related to faxes, 439 emails and the rest were SMS and pre-recorded messages, and others."
What's interesting to me is this: do the 439 emails that people complained about fall under this "do not spam" regulation? If so, companies who are sending out emails to members, assuming they're not restricted to any "do not spam" mobile phone registrar, might run into trouble if they did not realize the email messages were being delivered to the mobile phone device.
As email permeates into many different devices, a way to comply with all of the relevant laws will need to be addressed. A third-party service that specializes in email delivery would probably be the best way to stay compliant.
