FYI, my Evo 4G died the other day and long story short, I upgraded to the Evo 3D. I've gotta say, in my opinion, the 3D is a huge steaming piece of c _ _ p.
In the 4 days I had the device, it rebooted itself no less than 18 times, possibly more (not exaggerating). I have since returned it and gone back to my trusty Evo 4G. Unfortunately it has the new boot-loader, so I'm stuck in bloatware land with the stock ROM. Looking forward to someone finding a root exploit for the new boot-loader
