I finally got my iPhone4s 64GB from Sprint and so far paint me happy with the performance of device as well as Sprint network speed. Coming from HTC Touch Pro2 I find internet speed to be much faster on 4S. It may not be same as wi-fi but good enough to download apps from App store over 3G as well as pull down tons of emails from my 6 different email account, tweet & FB at same time without any major problem. I'm in upstate NY and so far so good. I even downloaded Speedtest.net app to see what it looks like and first test just now gave me speed of 0.68Mbps down and 0.54Mbps up. Good enough to do most of what I intend to do.
