Have you used LTE on your iPhone 5?

Having seen the big deal being made about whether or not the iPhone 5 will have LTE, I would like to know how many of you guys have actually been using it regularly.

I'm currently residing in a major UK city, and LTE won't get here until maybe late this year or 2014.

Could the iPhone 5 have made it just fine without LTE? This post isn't about future-proofing or economies of scale. It's just about the actual importance of having LTE on the iPhone.
