Namelesz (USA) : This is NOT a product review (for these you need to use third-party review sites with objective data in each review), this is just a warning for potential customers. If you can buy it elsewhere - do so. HTC themselves sell a "developer edition" of this phone on their site, which has 64GB of storage and is fully unlocked and supports same GSM/LTE bands, for slightly more than Amazon's current price. If you do not need extra storage space - Google sells the HTC One with 32GB of storage, fully unlocked, running latest Android version (unlike what you will find on Amazon), for a cheaper price than Amazon has. Google's version does not include HTC Sense, Blinkfeed or any other custom HTC software BUT some people do not need this and you can always flash the Google's edition with a custom ROM which includes all of HTC's custom software, for free, without losing the warranty.

M. Huerta (London UK): I have Verizon (I know, I know, but I have the grandfathered in unlimited data plan). I bought this phone because I may be leaving to school in London, and my current (Verizon) phone is CDMA/LTE and I need a GSM. I tried activating online, but was informed I needed to call Customer Service. I was then informed that even though it is an unlocked GSM and LTE phone (according to the Amazon website), I can't use it because it does not have the Verizon operating system/bloatware. So now I have a phone that I can not use unless I do leave the country.

 I Just Shop Here (USA): Cell phone is the most popular electronic device nowadays, there are more than 320 millions of cell phones in U.S, even more than the population of U.S. How to choose a cell phone becomes a headache when people want to purchase a new one. Actually there are some criterion we can use for it, like hardware design and unique features ,battery life and camera performance . In my opinion, HTC One is the best cell phone so far because it perfectly match all the criterion .
