I've had my Samsung Captivate now for almost a week, and I love it! The problem is sometimes I can't connect to the internet (not wi-fi). On the top of my screen, it won't display the E with the up and down arrows (no 3G coverage). It only shows signal strength and battery. When I try to get on the Android Market, It says something like "no network detected" or something like that. I can't access anything! I've tried battery pull, turning on/off, resseting default connection ( ATT WAP). I don't know what else to do. Is anybody else having this problem?
