Has anyone else noticed that Verizon's service seems to be getting worse? Lately I've been having 3-4 bars 3G, but I've been getting the message that the network is unavailable and to try again later. Other times I will have full 3G, then it cuts in and out a few times and goes back to 1-2 bars 1x, and it keeps switching between 3G and 1x so I can never load a webpage without hitting refresh a few times.
