Most people won't care about this, but I was riding around today and picked up full signal 4G on my Thunderbolt around 38th and Meridian. Speed test gave me 15mbps down and 4mbps up. I was only able to drive for two or 3 blocks before the 4G cut off. Nevertheless, I'm still having 3G data connections on the phone :-( 3G is either extremely slow or goes to 1x or disappears all together.. While my verizon iphone works perfect
