Think your $99 Nokia E71x from AT&T is all that? It might very well be, but you might just change your tune and turn green with envy as Nokia's Conversations blog has just posted a video of its successor, the E72, to YouTube and it looks to be quite a nice update. A 5 megapixel camera with auto-focus and flash, optical trackpad, 3.5mm headphone jack and S60 FP2.
