Hi all - I was surprised to see no line and plenty of stock at the Clarendon Apple Store in Virginia this morning, so I picked up a 32GB white AT&T model. AT&T's LTE coverage map says Arlington and DC should be covered by LTE. At home in Arlington, I have no LTE, only "4G". Just got to work in downtown Washington, and also no LTE. I signed up for the data plan thinking that might activate it and still nothing. Anyone else having a problem? If I can't get LTE, I'll probably exchange it for the Verizon model. Thanks.
