Verizon-bound Lumia 735 spotted at the FCC
The Lumia 735, and its dual-SIM version – the 730, was announced a couple of months ago and, together with the "affordable flagship" Lumia 830, was said to arrive at the US "soon". While the 830 is expected to become available through AT&T on November 7th, the Lumia 735, or at least the Verizon version, is rumored to be postponed until 2015 for reasons not yet known.
The Lumia 730 / 735 and Lumia 830 were announced together, the 830 being labeled as an "affordable flagship" by Microsoft, whereas the 730 / 735 are “the ultimate selfie and Skype phone”. The handsets sport Snapdragon 400 chips, 1 GB of RAM, large displays (4.7" for the 730 / 735 and 5" for the 830) with 720p resolution, and are some of the slimmest phones to come from Microsoft. They've been available around other regions of the world for a while now and why Redmond is taking its time to bring them to the US is unknown, though, it's probably safe to assume that it's due to the fact that Windows Phone is just not that high in demand in the States.
