Around 40-50% sprint likes to launch the market. Sometimes they launch it earlier, but around 40 to 50% coverage should be good, but not everywhere you go.
I Haven't been a lot of places, and I meant new lte, lol didn't know I had to be so specific. I've posted speed test and lte engineering on this before. Plus I have a gs3 (hopefully a gs4 before or during the summer).
To me it will be worth the wait, currently we are in a pre-lanched stage and I've seen some lte and I have better 3g data. 3g is great and I'm sure the lte will br to.
