I got my MX a little over a month now and the cell signal is continually bad. It's safe to say that I don't get even one bar of signal 80% of the time! I sent it in for service last week and the rep said that the antenna is fine, most of the testing came back OK. Then she continued saying that they are aware of a firmware issue that is causing this. I was stunned since I've NOT heard of anyone else here having that problem...is there? She also said that the next firmware will fix the problem. Anyone here has similar issues?
