Have had mine since Monday and started making and receiving a number of calls today. I've had 2 dropped calls, both at my home. Calls from other places were strong and clear.
I'm a little concerned about the 2 dropped calls. My iPhone automatically connects to my home wifi and I have more signal bars at home than I had on my VZW BB Bold.
One of the calls dropped as 2 emails were arriving. I was under the impression that emails wouldn't come through if I was using the phone, just like every other phone I've used on VZW. I don't want emails to take precedence over phone calls so I want to keep an eye on that. It's possible that the call dropped before I realized it and then the emails arrived.
