My wife and I just upgraded from iPhone 3s to the 5. We also switched providers from AT&T to Verizon, in part because Verizon advertizing and Apple salespeople were indicating that Verizon's LTE coverage is much more robust than Verizon. So I was surprised to note that smack in the heart of downtown Los Angeles, I get a whopping 1 to 2 bars of signal strength. Have I been duped, or is this standard fare for LTE signal strength?
