Samsung's Nexus S
might be the phone that helps take the convex style mainstream, but it's hardly the first -- take Motorola's crazy UIQ
"banana phones," for example. Looks like Nokia had at one time planned to introduce a slick curved candybar to the market, too -- the so-called 3700 Classic -- thanks to a video posted on Vimeo that has all the trappings of a professionally-produced teaser ad. The operating system appears to be Series 40
, slotting it below the company's Symbian fare and putting it in dumbphone territory. Word on the street is that this thing was probably canceled -- and though we can't get too excited about a Series 40 candybar, this could've been the pinnacle of Espoo's Series 40 line had it actually made it to market.
