Starting with the last update earlier this week, I have been having a hell of a time with this stupid phone. The biggest problem is I will have good (3-4 bars) signal and 3G, and when I attempt to make a call, 3G disappears and the bars disappear. Instantly. When that happens it just sits at the "Dialing" screen. As soon as I end the call all my bars and 3G will come back. I've tried turning the phone on and off and nothing helps. This is ridiculously frustrating. It has gotten the worst today. I can no longer receive calls either. I have been able to make only three calls today and the one call I did receive, as soon as I answered, it cut the call off.
