According to the filing, the Verizon-bound phone has network support for both CDMA and GSM standards and FDD LTE bands 3, 4, 7, and 13. Apart from that, little else of note is revealed by the document.
So far, rumors have led us to believe that the full retail price of the handset will hover around $600, and will likely carry a $199.99 tag on a 2-year contract with Verizon. While still on that page, we're also told that Verizon branding will be visible only on the back of the device, which is a nice change of pace (Verizon likes sticking those at the front, too).
Lastly, a bunch of invitations"One M8 for Windows" to a August 19th event to be hosted in New York are reported to have been sent out by HTC two days ago. Considering the increasing number of sightings of the alleged "One M8 for Windows", we'd venture a guess that this could be when the company will officially introduce the device.. According to another rumor, three days after the event -- on August 21st -- the Microsoft Store will start offering the special edition of HTC's current flagship. In other words, it won't be long before we know if that's true.
