OK Me and my friend we both have the evo and we notice today in Orlando fl that we were able to connect to 4g and use it.Don't know for how long or if it is a test but it work. here is a picture of my friend evo with 4g signal.
By the way we where able to make phone calls and use the internet at the same time.
