IPhone 5 on Sprint unlimited everything.is this what's best for me?

I've been looking around at phone stuff

I do want an iPhone for easy syncing to iTunes & keeping track of playcounts, and iPhone 5 is the best one of those out so there's that

But then for plans, it seems that Sprint allegedly offers the best in data, everyone else lies apparently

Others say "unlimited data" (AT&T, Verizon) but then really mean 6gb, others (T Mobile) says "unlimited data" and then choke your speed down to 2G once you pass the 500mb mark…

It looks like this allegedly would cost $100 down and then $110 a month. To have my ideal phone under an ideal plan.

So my question is… Am I missing anything? Is there any way to get the same truly unlimited everything on an iPhone 5 cheaper elsewhere?

Added (1). Well facebook is 1 thing, but I want to be able to stream music with Rdio and videos with youtube up to 16 hours a day if I want to O_o

Added (2). But also, Verizon basically already told us "Go *** yourself"… Some kind of past billing issue in our family with them or something:/

How much do you currently use with your current service?

Both the wife and I had iPhones with Sprint, but they don't have LTE and their data was as slow as a slug.

We eventually switched to Verizon that has LTE data speeds. Between the wife and I who sits on facebook 24/7 ~ we use a combined 1.5 gb per month. We have wireless at home and at the office. IF you are around quite a few Wi-Fi hotspots (home, work, coffee, or even some cars) then I would go with Verizon.
