No motion on eCSFB in the downtown area...still nigh-unusable 3G as of a week ago. I'm only trolling these forums now to see when downtown is on and speedy, so I can hop back on the Sprint network.
If you're out of contract (buying your own phone), might I recommend Ting. Sprint network, cheaper prices unless you need unlimited data. I got my sim from them in a few days.
Is there any further information on downtown Milwaukee light up of ecsfb? 3G is so slow as to be basically unusable, but I don't get LTE on my triband phone.
