Yep that's the idea. But it doesn't seem like any phones right now support using a DNS resolver. That's the main thing. And many phones only has numeric pads.
It's more of a marketing challenge than a technical one I guess.

But. I think the only true way of making this successful is an open source effort. And an ability for people to setup their own DNS servers. Perhaps I shall investigate Namecoin.
