My CDMA Galaxy Nexus on VZW was great at everything except being a phone. Call quality was awful, my signal constantly dropped, it was the only phone I ever owned where I encountered dead zones on my drive to work. Every single day, in the same exact spots, I would lose signal. I switched to a GSM Galaxy Nexus a few weeks ago, w/ T-Mobile, and the worst that has happened is my HSPA+ dropping to HSPA.
