We all know AT&T's network sucks but I'm convinced IOS is specifically designed to dupe us into thinking we have 3g all the time when we don't. I've noticed that if I flip on my iPad it says 3G up in the corner, but the second I open up Safari to surf I get Edge. Then if I close all the tabs in Safari and get out of it, vioalia! it says I have 3G again. BS.
