Earlier this year there were reports of Apple buying a bunch of glass cutting machines of the type to make curved bezels.

So I'm thinking that since the 4 had glass bezels front and back and the problem with the iSpot - why shouldn't the 5 have curved glass front and back, forgoing any metal on the outside?

I don't think the many shopped images showing iPad or Touch like phones would be innovative in style. Been there, done that.
