I was away with the kids visiting my folks last week. I do not have 4G service where I live, but my parents do (right outside Wash DC). I love my phone with just 3G, but I couldn't believe how much more awesome this phone got with 4G. I've had my TB since March and I've gone up to visit my folks many times before, but for some reason, 4G on my phone seemed shotty. I would lose connection all the time and would always just switch my phone to 3G only. I just downloaded the latest update last week (prior to which my phone was just stock) and didn't really see a major difference in performance. I turn on 4G when I get to my parents house and start playing with my phone and it does great. It didn't loose connection overnight either like it always did before....it didn't lose connection at all while I was there. HBO GO on 4G is great and the best thing out of all of this was that my Navigation GPS connection was lighting FAST! It only took 1 sec to start up. The update must've fixed it because I used the GPS in 4G and in 3G Richmond and both times it was instant connection. I did use GPS Status to help prior to the update, but it still took 30-40 seconds to connect. I've never seen my phone navigation connect in 1 second. I'm now extremely jealous of all of you who do have 4G and can't wait for it to reach us here in SW VA. I really love this phone, always have!!
