Voice calls, even with 3 bars, whether it shows 1x or 3G, on the iPhone4S are worthless. The calls will drop out, not might. Other parties can't hear me when they do connect. I contacted VZ while at work, but they want me to t-shoot from home (ho hum...and do what? I can't update roaming, although I question I'm trying to hit a roaming tower from home), the call will fail. What does it take to have VZ do a signal strength test in my area and determine what can be done? I certainly can't call from home, and there is no live chat available, even though it's during the reported available times. I can't say AT&T is much better, but if any friends ever show up with an AT&T phone, I'll sure closely examine their service.
