According to MacRumors, well, more like according to iPodObserver the new 3G iPhone will sports an all black glossy back finish.  As Macrumos points out, it’s unlikely that these are accurate, which is further reaffirmed by iPodObserver’s recent misquoting of a Gartner analyst.  In any case, it’s not totally unlikely that Apple will change up the look slightly to attract new peeps.  I do have to question how scratch free an all black back could remain.  If it were up to me, I’d get rid of the stupid metal rim lining the outerface of the iPhone.  I think the iPod Touch has a much sleeker finish.
