Currently, there is no 4G iPhone in the U.S. The only network, as of today, that carries the iPhone is AT&T and they don't allow the iPhone to connect at anything above 3G speeds. Tomorrow Verizon is set to announce that they will carry the iPhone. It remains to be seen if it will run on their LTE (4G) network. I doubt it.
well i have heard of it u probably got the wrong plan i heard that there is a plan were u can only see pics or do nothing except see pics and play games and the other plan is doing everything u didnt get that plan
Actually nobody really has a 4g satellite yet there are just phones that will be capable to access that satellite when available. Its happened before like when 3g phones came out there was really no 3g satellite until about a year later. Don't worry because im actually answering this with my iphone 4 and it like most other at&t phones works fine with any signal available
