I have confirmed that ATT LTE is working in the Kendall area of Miami. Speedtest showed 11 Mbps download speeds on ATT LTE in Kendall -- SW 147 AVE - SUNSET DRIVE. As soon as the iPad was moved a block from that area, LTE went away. Also, LTE signal on iPad lit up right outside of Dolphin mall... Is anybody else in the Miami area getting some ATT LTE before the official launch???
