Two months ago I upgraded my smartphone to an iPhone4. Immediately, I started dropping calls. I called Verizon and they sent me another phone. It, too, dropped calls all over the place. I just activated my third iPhone today, and it's dropping calls. It doesn't matter where I am, calls drop. My smartphone didn't drop calls (all to the same numbers and from the same places that the iPhone drops). Verizon says it isn't the iPhone. But my last three cell phones before the iPhone hardly ever dropped calls, but now most of the calls I make end with four beeps and a "failed" message. I am really disappointed.
I still have the same problem but its not the phone's fault, its our fault for buying it!
