Got my RAZR last night. I haven't experienced the 4G/3G flipping yet, but I am noticing the slow down I've seen talked about with LTE phones, at least Verizon phones. A few hours ago my speed test was 10Mbps. An hour ago it was 6 Mbps. Now it's 4 Mbps. Has any progress been made on this as to why it happens and how to avoid it and get my speed back to normal, even if it's just temporary?
