I ended up having the MT(I was one of the first people to have one actually got it before it was officially launched) stop charging with ANY charger. (Usually I just use my Nook Color charger for ALL of my phones/tablets/devices and it had always worked with the MT for about 6m.)
The first time that it happened I noticed fairly soon and a simple popout the batt then back in did the trick, then about a month later(December) it got to the point where it wouldn't charge(no light indicator/wouldn't reboot etc.) with ANY charger even the packaged one. So VM sent me another battery, still no go(messed artound with it for a week as I still had the OV to fall backon), called a second and got a phone sent out which showed up the next day IIRC(or the 2nd day after FAR more quickly that I expected).
2nd one it still ticking, and I've got a second battery now as VM didn't want my old batt or the replacement that they sent me back...
But yeah, I'll be pissed it it reoccurs esp IF it happens after the 1y std warranty is up, but in that case it might be my sign to go with T Mobile(since they're out of danger of being steamrolled by one of the evil empires ATM) and actually truly topend multi-core cortex-a9 CPU phone and their $50/m plan.
(The OV was just as crippled as I remembered it to be... It was a crime to make a modern phone with so little RAM and internal storage!)
