Hello all! I just got a Bionic yesterday, and I am loving it except for one thing. The person who sold me it said that sometimes that when switching from 3G to 4G, it could stall and I would get no net. She said that when this happens, just switch it to airplane mode, and back again. I seem to be doing this a LOT, ESPECIALLY when I get the notice that a wireless network is available. I also have noticed that my my 4G icon and signal meter in general seem to switch back and forth from a blue to a greyish white. What causes that? Are these related?
