HTC Twitter Account for its UK division has Seemingly Confirmed the design of the upcoming HTC One. In a graphic posted as the background for the account's page (and on Facebook as well), you can see not only the date of the 19 February event listed, but also a quick glimpse of the white back/bezel of the handset.
The graphic lines up nicely with the press shot leaked this week by @evleaks, as seen below. The press shot didn't provide a look at the back of the device, but the photo on the Twitter account appears to.
According to various leaks, the handset will feature a Quad-Core Qualcomm Processor ( predictably ), a 4.7-inch 1920 x 1080 (full HD) display, 32GB of internal storage, no microSD card slot, 2GB of RAM, a 13-megapixel rear camera, and 2-megapixel front-facing camera. HTC's newly designed Sense 5 is also said to be included on the handset.
