A Samsung Windows Phone 7 was recently caught up against an iPhone, giving us a little size comparison. What appears to be the Cetus is just a smidgen longer and wider than the iPhone and maybe even thicker.
What's a little confusing is that we've known the Cetus to be tagged the Samsung SGH-i917. The Windows Phone 7 device pictured is tagged the SGH-i916. The distinction is likely that the i916 is headed to the Canadian wireless provider Rogers, while the i917 is AT&T bound.
