After being throttled last month I have started paying very close attention to my bills and data usage. As I scanned my latest bill I noticed that my iPhone 4S is apparently on the "AT&T 4G" network. My iPhone 4S still displays 3G in the signal bar. Am I supposed to be getting faster service? I am not paying anymore money. I have not noticed any faster service since getting my 4S. Can someone explain this to me? And what is AT&T "ENHANCED BACKHAUL"?
