Samsung SGH-E316 / SGH-E317

I was wondering if there were any good sites where I could download real ringtones for my E316 for free...I read about wap.truepolyphonic.com, but I got a little confused with mMode and everything. If anybody has knowledge on truepolyphonic, do you think you could explain how I would go about using it? Thanks. Also, is there a way to set a picture (not the picture ID, just to replace the ball on the display) on the external display of the phone? I don't like the ball and would like to use a different picture, also from truepolyphonic. Thanks in advance.
