answer:From phonezoo.com Help/Support section… Why is my phone not supported? We are sorry! If you are in this situation, you probably have * a phone that does not support truetones OR * a carrier who does not allow third party content providers to work with your phone, e.g. Nextel OR * a carrier who has crippled your phone, e.g. some models of V3 RAZR on Verizon You are welcome to try to make it work. If you do, please do drop us a note at Support/Feedback. /*
