The unlocked HTC One is compatible with AT&T and T-Mobile's network. And we should point out that those looking to take HTC up on this deal will have to be subject to credit approval. Only "well-qualified applicants, subject to credit approval" can get the HTC One direct from HTC for $25 per month. According to HTC, "other applicants may receive different financing terms or offers based on creditworthiness."
While HTC's cyberweek promotion is over (a subsidized Sprint or Verizon HTC One for $49.99 on contract), there are still four weekly drawings left to win an HTC One from HTC. You can still enter before midnight Sunday to make the drawing scheduled for Tuesday. From Monday, December 9th, through next Sunday, you can enter for the drawing scheduled for December 17th. There are two more entry periods after that (December 16th through December 22nd and December 23rd through December 29th). To enter, you can email a picture to NYC@HTC.com or tweet it to @HTCUSA on Twitter and tweet the hashtags "#HTCinNYC" and "#US". You also will be entered in one of two grand prize drawings with the winner receiving a 24K gold plated HTC One valued at more than $2500.
