There will be very little mystery to the All-New HTC One when it launches next month. In addition to the multiple leaked pictures we’ve already seen, @evleaks has now posted a leaked press shot of the device that clearly shows ATT’s branding on the rear casing. Other than that, the leaked image pretty much shows us everything else we’ve already seen about the All New HTC One including its dual rear-facing cameras, on-screen buttons and light sensors that have been shifted over to the right-hand side of the phone next to the front-facing camera.
