Sure, Microsoft's just put up the biggest Windows Phone in the world in NYC, but that doesn't make the US arrival of the second biggest Mango phone any less exciting. While the HTC Titan launched in Europe just last month, AT&T has just announced that it will begin carrying the mammoth 4.7-inch phone on November 20th for $199.99 with a two-year contract. That goes right up against the new Samsung Focus S (handy chart comparing them here), but it is nice to see AT&T's dishing out a hearty selection of WP 7.5 before the holidays. You'll find the official word at the source link below and our full review of the European version right here.
