Not to mention that the only "4G" network currently available for cell phones is Sprint. The "4G" in the iPhone is not a 4G network, just the 4th generation of the device. They're still on the same old junk AT&T 3G network.
Sprint is rolling out a 4G network right now, as is Verizon (who has promised to provide full 4G coverage - equal to their current and class-leading 3G coverage - by 2013). AT&T is thinking about something named 4G, but no plans until 2011 at the earliest.
I'm sure the new iPhone label of 4G wasn't by accident...;)
I was with Verizon for the last 6 years. I live in the hills [Hollywood] and had a lot of dropped calls. It was annoying but I still like Verizon.
I did stand in line for the iPhone 4 and reluctantly gave up Verizon although I have had no dropped calls with AT*T although I am expecting them.
I also have the 3G iPad with AT&T’s unlimited plan which they pulled immediately. So far, I have had GREAT reception, although i attribute that to being in a big city.
