ATT to launch LTE 4G network

I read the MacRumors.com article but don't really understand what enhancements I will realize on my iPhone.

Can anyone put it in language a 13 year old would understand. Well, not today's 13 year olds. [ smile] 1949 13 year olds. Ha.

Edit:

Verizon jumpin on too!

Verizon LTE in 30 cities by year end, AT&T aims for mid-2011

Both AT&T and Verizon are moving forward with their 4G/LTE networks in the US, with one launching by the end of the year and the other going commercial by mid-2011. And, with the recent approval of the first LTE phone by the FCC, the door is opening for a trickle, then flood, of new LTE devices to hop on those networks.
