Please don't start any problems with any other members. If you're upset because you Galaxy Nexus can't hold a signal, you shouldn't take it out on others.
I too have inconsistent 3G/4G signal with my Verizon Galaxy Nexus 4.0.4. Whereas 3 others with Verizon iPhone 4 would have ~2 bars and functional data, I'd have 0 bars and no data connectivity at all. This happens quite often, as my wife is one of Verizon iPhone owners sitting next to me with no issues. Even at my work (Manhattan 12th floor by window), the signal goes from 4G 4-bars to 3G 2-bars to no data signal every few hours throughout the day.
