So far I am very annoyed at the fact that my 4S is not performing any differently whatsoever from my 4 on speed tests. Depending on time of day, both devices average about 1-2Mbps down, 1 Up, and 100-200 ping. I have yet to see any difference between the two devices and have tried at multiple locations around town. Is there any way to verify that my 4S is actually using HSPA+? If my towers are just congested in this area (South Denver) then fine, but if this is some issue where AT&T has my account setup wrong, I want to know. AT&T is clueless when I call them. My account does specifically say "Data Unlimited for iPhone4S" while my other phone says "Data Unlimited for iPhone", so that should indicate I am on the 4S data plan if that is necessary to get HSPA+ speeds. Would love any help or insight on this? Thanks!
