Very nice site for a wide variety of music ring tones. The site is clean, easy to navigate and has a good selection of ring tones, ranging from mainstream (Kanye, Beyonce, Linkin Park) to the offbeat (Minor Threat, Joan of Arc, Peaches). So far this is my favorite ring tone site.
Funtonia has a variety of plans, so you can sign up for the one that suits your needs the best!
Once you have an account you can access the site from your mobile phone at: wap.funtonia.com
Very, very cool!
