After the bearing failure on my MR2 Turbo, 3SGTE, I’ve been investigating bearing failures.
There are a couple of very good guides which provide an example of a number of different bearing failure modes.

More examples after the break
After dismantling my 3SGTE, we found that all of the bearings had picked up and one big end had spun completely and ripped the bearing in half. Most of them looked like this:
The crank was also scored and I suspect the con rod with the spun bearing my have gone oval too.
So, I have just bought a lovely new HTC One, and am mostly happy with it, although the screen is a bit too big to use one handed and the network connection seemed a bit slow. I still haven’t managed to do a proper test o. the mobile network connection, but I have gotten to the bottom of why the WiFi connection was so slow.
