Where and when will 4G from AT&T be available to me? AT&T is constantly deploying upgraded backhaul to deliver 4G speeds. By the end of 2011, we expect approximately 2/3 of our mobile broadband traffic to be delivered over our enhanced network. For information on currently available 4G markets, see 4G Speed from AT&T and select the Coverage map. Just makes sense to me that iPhone 5 was delayed so 4G could be in place when it's launched. I think waiting until iPhone 6 would just be to long for the iPhone not to have 4G with all the billboards, commercials and other marketing that is taking place surrounding 4G. I know there are two schools of thought on this so what do you think?
