So I just got a Lumia 920 as a second device (1st: Htc One X) . So far its kind of confusing as far as navigating and multitasking, &etc. I was a true tech savy person when it came to android and I have decided that I will flip back and fourth every now and then from the Lumia to the One X. Is there anything I need to know as far as Windows Phone 8 , Lumia 920 or any kinds of guides to beginners of the OS?? Thanks!
