Ok I have been testing out my 4S data speeds all over town and I am only getting between .5 and 1.5 mbps. Thats pretty slow right? When my phone is tapped into my wifes t-mobile internet it gets up to 6.48 mbps in the same spot. I called AT&T and they said that my city (Yorba Linda, CA) has very good 4G coverage and that I should be getting a good data signal. I got better speeds on my 4 then I do on my 4S. Could it be the phone. I mean it could have a defective chip right? I'm thinking about taking it into apple and testing it against the phones they have on display and seeing who my phone compares. What do you guys think?
