The first time we saw the rumored Supersonic we were blown away. HTC and Google had just wowed us with the Nexus One , and here we were looking at something even better — a 4.3-inch phone with WiMAX wrapped in a white body. This prototype was buggy and had abysmal battery life, but it was real. Four months later it landed in our hands at Google I/O . We’re of course talking about the EVO 4G which went on to become a runaway hit for HTC and Sprint as the first ever 4G smartphone in the US. And here we are, a year later with the HTC EVO 3D , the legitimate heir to Sprint’s mobile kingdom — at least until the Motorola Photon 4G comes along. When we first played with the 3D-capable handset at CTIA we were suitably impressed, but we left with a lot of unanswered questions. How do the 1.2GHz dual core processor and qHD display affect battery life? Is 3D a compelling feature or just a gimmick? What is 2D camera performance like with the lower specced camera? Is the EVO 3D a worthy replacement for the EVO 4G? Find out in our review after the break.
