Black Holster Case with Swivel Belt Clip for Apple iPhone 3G and 3GS
I've had this belt clip for a few months now.  I can tell you that it attaches easily to my belt, and that my iPhone 3G attaches easily to the clip.  Taking it out of the clip when needed is a \\"snap\\" (please pardon the pun).  It snaps out easily, but not so easily that it would ever fall out on its own.  I have zero complaints about it.  So far, so good.
