No "sync ringtones" tab

Question

I have just got an iphone 3g and desperately want to select my own ringtone. I have successfully created ringtone files, and they appear in the Ringtones section of my library in itunes. BUT I cannot drag and drop them onto my iphone. Nor do I have the Ringtones tab to sync between the two. I have checked ringtones in Preferences, but I still do not have the tab. I think maybe the latest version of itunes doesn't allow this....?
.....which still leaves me without any decent ringtones. I have looked at various apps to create ringtones, but will I face the same problem when I come to sync them?? How do I get around the no "sync ringtones" tab problem?
Thank you
