If you have a lte device let us know how your signal is doing today.
Saw the bionic section complaint about lte issues and I just made an angry post about my nexus not being able to keep a 4g connection. If 2 separate lte devices are having 4g issues it could be an outage.

When you can get a good 4G connection, it works just fine. More often than not, it fails to connect and falls back to 3G; with varying rates of success (sometimes 3G icon goes blue, other times it simply disappears) - if you fiddle with it enough, you finally end up with a 4G connection; probably due to the laws of probability.
