LTE? WTF?!

Received my iPhone 5 bright and early today. After a few SIM related glitches, I was able to get online and test out the new LTE connection. First, a comparison with standard WIFI. Below is my speed test of my home network (Comcast Performance - 20MB down and 5MB up per their specs).

Pretty respectable. I sometimes can get 10MB-15MB down but 5MB+ is the usual norm. Now check out the speed when I turned WIFI off...

Holy... freakin'... shnookies...

I have a feeling that I'm about to be throttled by AT&T quite frequently...
