Now that it looks all but certain the Verizon iPhone will be announced tomorrow, one of the questions that comes up is will users switching from AT&T help take the load off and create a better level of service for everyone?
First, a personal anecdote: I left Montreal to fly to CES 2011 last Tuesday. In Montreal the iPhone is fast, like HSPA 7.2 fast, with nary a dropped call and lost network signal, and a battery life that lasts as long as Apple's TV commercial suggests.
I switched planes in Charlotte and began to roam on AT&T. My iPhone 4 showed full bars but I kept getting a popup saying there was no network connection. That means the tower was broadcasting but there was no backhaul behind it. Like if your home Wi-Fi router is fine but your broadband ISP is down -- lots of radio, no internet.
