I actually prefer AT&T and nokia phones, especially in this area, there is no way in hell you'd ever catch me on a verizon service plan; or with anything other than a nokia for that matter.
Not too many people want to even deal with that model/type of phone for note. There aren't that many sites that do "Free" ringtone's, http://www.mobilesmarts.com
does some but their site is the buggiest sob i've ever seen...
The reason they don't support them, is because, honestly, both suck.
