On a site we're building we need to serve up ringtones to users. Seeing as there are so many formats, I'm looking for a partner who would convert our uncompressed audio into all the different formats, host the ringtones, and provide an interface for users to get and install them. They would all be free ringtones and we would deeplink to a page on the partner's site. I am expecting we would pay them for this service. Has anyone worked with someone like this?
