LTE is overrated and not worth it since I spent about 98% of my life on wifi, and I haven't missed MMS because of iMessages.
Not worth it for you
I really don't think having fast, hassle-free internet access on the go is an edge case. Isn't that one of the main reasons people buy smartphones?
ha - I had 6mb dl on 4g w/ AT&T iPhone 4S and moving to the iPhone 5 w/ LTE made it 24mb dl. Overrated? Maybe for you but, whenever a company triples my service and doesn't charge me more money, I'm happy to take that deal.
