After a day 1 with the the Evo, my feelings are mixed in regards to 4G. When I can get a signal, its great. But that's the thing, holding a 4G signal for long is tough. It seems to only be useful if you're sitting somewhere with a solid signal. It works great in my living room, but awful in my bedroom 15 feet away. I plan to test it throughout Chicago over the next couple weeks. I'm currently using the internet sharing feature via usb and getting great speeds. Unfortunately, it appears the internet sharing feature has been disabled for 3G tethering.
