Q: What kind of mobile phone do i need to use sound of oo's ringtones?

A: You will need a mobile phone that supports the mp3 format, and allows you to use mp3 files as ring tones, message tones and alarm tones. If you have an iPhone, use the "iPhone m4r" versions of the tones. iPhones don't let you use outside message tones though.

Q: Why do all of the ringtone names start with "oo"?

A: oo is the sound of sound. Furthermore, since sound of oo is a swedish based project, all of the ringtone names are swedish words we like begining with the letter "o".

Q: Are all the tones free?

A: Yes. We like giving good sound design to the world.
