I've been trying to get some ringtones for my Motorola T720, but I get an error every time i try to select a ringtone. I get error 406: not acceptable/invalid content type. I've tried all the links on http://v22.net/test4.wml and none work. I can't get to the MMF site, it says that I'm not authorized. I am on Verizon wireless. Any suggestions?
