I've been an iPhone user since the iPhone 3. I just decided to bought a Lumia 830 instead of a iPhone 6...and I love it!...i love it so much that I'm thinking about changing it for a 1520, but, is it a good idea? Or 1520 is soon to be obsolete (because of the time it's been out) ?? Any comment please. My doubts are because of future support to the 1520.
