[One (M7) Android Development] streetster:
Cheers Vomer! Changed my CID from HTC__001 to 11111111 (maybe unnecessary tbh)....

I had already s-off'd and upgraded to 2.24.401.8 shortly after getting my phone... Just been through a bunch of flashes (better safe than sorry).

For anyone that cares, I did a fastboot getvars all on the way through so you can see what changed:

Not sure precisely how much difference it will make in the day to day, but might solve a few of the random SODs I get with Cyanogenmod. Who knows!
