As far as using the word "facebook" in a domain, such as "facebookringtones.com" or "facebookiqtest.com" (just examples), I'm aware that it's copyright infringement but have they actually gone after anyone for this, or do they usually not bother?
As another example, how about instead of "facebook ringtones" you called your site "fb ringtones" and used a navy/white color scheme?
