HTC One can get set up on your desktop computer24
Even before your HTC One has arrived, HTC Get Started will show you on your computer screen exactly how certain wallpaper will look on the 4.7 inch panel on the unit. Half your work will already be done by the time the phone arrives on your doorstep. For many, this will be a big help in setting up the HTC One while those who don't mind getting their fingernails dirty can always do things the old fashioned way, and take care of business on the phone itself.
