Cracks in the case are the scourge of every cell phone owner. To wit: The Palm Treo Pro, iPhone and Palm Pre are just three of the more recent high-profile phones that have suffered some apparently random plastic breakage. Add the Sony Ericsson Xperia X1 to that list.

But cracks in cases are nothing new. What you see above, however, is interesting in that we get a good look at a slight design change in the Xpeira X1. (Look at the 90-degree corner there to the left of the numbers.) Any engineering types want to chime in on structural integrity of the two designs?
