I haven't felt the urge to switch from my Android but here is the review of iPhone for those who are:

Summary:
"I think it's important to note that we are almost four years removed from the initial excitement of Apple's first phone, and there are reasons not to buy a Verizon iPhone. Nowadays there are many strong competitors on a variety of providers and from many different manufacturers. This iPhone isn't even on Verizon's new 4G LTE network, which makes it slower than some of the most exciting phones available today. But the unfortunate reality of these super-fast devices is that battery life is not so grand. Apple and Steve Jobs have always focused on performance in a variety of metrics, and if super-speeds have the potential to kill battery life—perhaps the most important factor in any mobile device—then it's unlikely we'll see a 4G iPhone any time soon. Considering the performance I found with the Verizon iPhone, I do not see this as a problem.
Overall, I liked the iPhone with AT&T, and I like it even more with Verizon. I expect many other consumers will feel the same. Sorry, AT&T."
