When you go to purchase the ringtones, you will see a list of supported mobile carriers. This is the list we have for this time. While Blizzard does not have direct support for the mobile ringtone applications, in the FAQ page you can see that we have a form for contacting Echovox with any questions not covered in the FAQ.
You may wish to ask them about future carrier support or any other concerns you have about downloading the mobile content to your phone.
