From Android Guys:
New details hitting Unwired View today line up nearly spec-for-spec on early rumored hardware for the upcoming HTC Myst. Also known as a Facebook phone, this is about as close as we’ll get to another handset dedicated to the social platform.
It’s not quite clear when the HTC Myst will arrive however the phone appears to be locked for a 4.3-inch 720P HD display, dual-core 1.5GHz processor, 1GB RAM, and 5-megapixel rear camera. The front side will feature a 1.6-megapixel camera and the Myst will also get the standard fare of connectivity (LTE and HSPA as well).
Of course, the HTY Myst should also come pre-loaded with Facebook, Facebook Mesenger, and Instagram.
