Looking forward to 64-bit smartphones, but not sold on Sprint's incoming budget handset? HTC has another phone for you -- an unnamed device that it claims will be the very first 8-core 64-bit smartphone on the market. HTC teased the smartphone on its Weibo page, showing a mock-up of the device's corner featuring a camera, some proximity sensors and a metallic-looking blue outline. The octa-core processor probably means this is a mid to high-end devices (unlike the model outed for Sprint), probably with a Qualcomm-sourced processor like the Snapdragon 615. Curious? You'll find the teaser image after the break.
