If you're interested in the OnePlus brand and didn't want to go for the full 5.5" of the OnePlus 2... well the X has been... interesting to say the least.
And it'll be available for purchase for those that have their invite ready on November 19th
What does the X version offer?
16GB storage + microSD
13MP / 8MP
Now there has been some issues with the US about what bands it has for LTE, but if you check the bands there is overlap on 2/4/7 (Bell and Rogers are 2,4,7; SaskTel, Telus and Videotron use 4; yet only Bell shows using the 1900MHz - but checking http://www.willmyphonework.net/ says it should)
