As soon as someone gets their hands on the Verizon iPhone, PLEASE grab all sides of the phone (preferably in a lower signal area) and see if the call drops. I would think because they had to modify the antenna (CDMA) they would address the attenuation. This is the main reason I returned my AT&T iPhone4, couldn't stay on a call. For those of you who have never owned an iPhone4, you are in for a treat!!! If it performs better call-wise I am probably back in, obviously going from 3G to EVDO there is going to be a data speed issue, but maybe it won't be that bad...
