Amazingly fast. None can come close to this awesome phone!
I don't have 4G in Nashville.... I am visiting family in Raleigh, NC which does have 4G.... It really depends on where you are.... I was in downtown Raleigh and I got twice as fast speeds with 3G vs 4G.. While at my parents house 4G is awesome when your outside on the deck or front porch... Not bad and still fast as long as your near a window... Get in the living room in the center of the house downstairs and all of a sudden the signal is less than 1 bar and fades in and out....
Under optimal conditions 4G is great.... but right now even in an area with so called full 4G coverage the coverage is spotty at best... Either way I still love the phone.... kind of disappointed in the 4G coverage but even on 3G it's an awesome phone...
