Remember the YotaPhone, that smartphone that has a standard front-facing display and a second, e-paper display on the back? Well, the successor to that quirky Android-powered smartphone, the YotaPhone 2, could be making its way the United States later this year if its able to raise enough money through its crowdfunding campaign on Indiegogo. Should it come to America, the YotaPhone 2 will cost you about $600 unlocked and off-contract.
