Three Dees and Four Gees. That's the Evo 3D. But it's more than that: The screen's a killer 4.3-inch, 960x540 auto-stereoscopic display, meaning it's almost as high-res as the iPhone 4 and pulls off 3D tricks without glasses (like Nintendo's 3DS).
Inside, you've got a dual-core 1.2GHz Qualcomm Snapdragon 8660 processor, so it can play back (or capture!) 720p video in 3D or 1080p video in 2D. (And Android 2.3 means you'll feel the full snappiness of the chip—depending on how heavy the latest version of HTC's Sense interface is, which now has a "carousel" desktop.)
The issue with 3D isn't that it's bad, per se—it's that there isn't enough content for it, unless you're talking about Nintendo's 3DS, which is gonna have a constant supply of quality content. It's still kind of iffy for the Evo 3D, unfortunately. Sprint's working with Blockbuster to deliver 3D movies and developers to create some 3D games, in addition to Google's YouTube 3D action (which may prove to be the most robust source of 3D content). Hopefully it's enough, but one phone is hardly a whole 3D platform. Fortunately, you can alleviate the problem to an extent by shooting your own 3D photos and video with the Evo 3D's dual 5-megapixel cameras (no word on which 3D format it's going to be shooting in or what it'll be capable of playing back—the problem we had with our last 3D camera). Oh, and of course you can switch 3D on or off at will, with a switch. If you want, you can move 3D content wirelessly to DLNA-compatible 3DTVs or via HDMI as well, though you'll need to put on your stupid 3D glasses at that point.
BTW, early impressions confirm our main fear about the 3D after time with the 3DS's similar screen technology: The 3D viewing angle is very tiny. But in 2D it apparently looks fantastic.
Powering all of this? A beefy 1730mAh battery (compared to the original Evo's 1500).
There's no pricing info or hard release date—"summer"—but all in all, this is the most impressive phone HTC's put out in a while, and may be the Sprint phone to beat this summer, whether you're into 3D or not. And I'll be the first to admit: 3D photos? They're a nifty trick.
