As of around 11:00PM Tuesday night, 4G is up and running strong in Gainesville, Florida.
Speed test app on my thunderbolt is show a maximum of 19.85 Mbps down and 9.87 Mbps up in with 4 bars.
My thunderbolt hooked up to my computer through easy tether is showing a maximum download speed of 9Mbps. The mobile hotspot gives me about 14mbps max download speed. Both easily fast enough to watch netflix in HD.
On the fringe of 4G coverage near Santa Fe College where I work, I can get 4G with the switch app. (by putting it to LTE only mode) Otherwise it tends to want to go back to 3G. Even still, using easytether, I get 6Mbps download speed on my computer! On the very edge of coverage!
Anyway, I'm a new member. I've been following this thread for info ever since I found the site and thread looking for info when 4G blipped on in Gatortown!
