Hello, Recently the Internet stated offering these new domains called
".mobi" domains, which are/will be used for accessing sites using via
mobile phone. Well I was able to acuqire the domain
"http://www.mtvmusic.mobi". And I really want to sell this domain back
to MTV studios. How would I contact the correct MTV studios dept and
let them know a fellow Entertainment Leader has their domain? is their
a possible Phone Number? Email? Website?

To the extent that you are, as you say, an "Entertainment Leader," I
presume that you have access to attorneys who can advise you about
cybersquatting, the Anticybersquatting Consumer Protection Act, the
Uniform Domain Name Resolution Policy, etc.

If you do contact an attorney, I suppose that you might want to
mention that you've stated that http://www.mtvmusic.mobi is "their
[MTV's] domain."
