If you fancy looking at some of the things that make a device tick, ETradeSupply has a new video posted up showing off some BlackBerry Z10 parts. No surprise really, given the fact the whole device has pretty much leaked at this point including the same parts previously but it does reconfirm a few things in case you weren't yet convinced. Things such as the existence of a 4.3" inch display, front-facing camera and of course that LED notification light.
Oddly enough, it seems they have parts from more than one device in their hands, which could translate to them having pre-production models mixed with final versions or they possibly have parts from multiple variations of the L-Series devices. Alas, even they don't seem to know at this point what they have other than to say that they know they're different.
