+1 (not verizon, but a Dutch Provider) from almost full 3G to "no signal" in less than a minute. After that a few minutes only GPRS and up to 3G again.
One problem, several solutions, but none of them worked for me. Using a network app I found out my WiFi connection could drop while switching from 2.4 GHz to 5 GHz...and back. Once I had set my router on 2.4 only the problem was over.
