I'm not an expert on the subject, but I have the Iphone 4 on Verizon's 3g network, and I am satisfied with it. I wouldn't recommend doing battery-intensive things like watching Netflix on it, but to each their own. I also don't know much about data plans either, I just pay 100 bucks a month and I get unlimited data, which I am satisfied with.

With all that said, the main bonus of having a smartphone for me is the apps. Before I had a smartphone, I never used apps or anything, but I tell you, I've got a bunch of different apps on my phone now, and they make everything super easy.
