Nokia

I have some general questions before I buy this phone and hopefully one of you can help me. I wanted to know how to download mp3 ringtones onto it and what other features does it have that makes it special. I am switching from a moto V710 and from verizon to cingular because of the whole recall issue and their customer service. I have been waiting for 2 months for a "proper" replacement and they have had me waiting. Please get back to me. Thanx.
