I just bought AT&T 4G LTE White iPad. I am very confused by AT&T's coverage map. From Apples website, I click on coverage for 4G and it takes me to AT&T's website. It says there is 4G in my area. But what about 4G LTE!? In the key on the bottom it only says 4G not 4G LTE. Anyone know where I can see a full coverage map of 4G LTE!?
