Storm is not a get it now capable device. Thusly, you wobt get vzw tones on it. Just use your own tones and load them into the "ringtones" directory ob the storm.
I would have to say either it was a mistake, or there is something new I haven't heard about (been a VZW customer over 11 years and have had mostly "dumb phones"). However, I just went to vzw.com and checked the ringtones page in featues & downloads ... the storm wasn't showing as available.
