So if I'm traveling and my A T & T connection has 5 bars but it says E....does that just mean there isn't 3 G service?? My Verizon phone works great (figures! I guess the commercials about Verizon being better are true!) I don't get it...I do have a connection, just slow. Wifi locked here (bummer). I guess I just don't get why if it has 5 bars it says E? Error??
