Regarding the invalidated patents, if you read the blog and the Office Action within ( http://www.scribd.com/doc/274897046/15-08-05-Non-final-Rejec...), this was due to the priority date being moved forward due to a technicality in claiming priority to their own previously filed patent. As a result, previously excluded prior art came into play, including Apple's own previously issued iPhone design patents, which was actually on simply different aspects of the exact same design. As such, although the patent was invalid, it is inaccurate to say the design itself was "obvious" per se (although I really don't understand how obviousness works in the world of design patents).
