Curious: What happens when, during a call, you lose signal and don't recover it? If the call doesn't drop, does it just stay connected, waiting for the signal to come back?
I think the point is that it wasn't ever a complete loss of signal. Signal strength drops a little, maybe the baseband turns up its gain and burns a little more power, and the call stays connected.
You didn't have to hold it a particular way - you had to avoid holding it a particular way. I had one for 2 years and didn't experience dropped calls beyond expected norms.
