The contest runs until 11:59pm PST on January 5th, 2014. HTC's judges will then decide which entry is worthy of winning an HTC One. 12 units in total will be given away with 6 to be awarded to entrants inside the U.S. with the remaining 6 heading for winners outside of the states.
HTC does have one request. Do not use a device from another manufacturer as an example of a bad gift. In fact, Taiwan based HTC prefers that no other corporations be named in your entry. The contest is open to those 18 years of age and older who are residents of the U.S. (including the District of Columbia, Canada, Taiwan, The U.K., Germany, India, Singapore, France, Hong Kong, Vietnam, Australia, and Malaysia. Good luck!
