I've had an issue with my 3G data turning off lately, even though data was turned on (power bar). No matter what I open (mail, browser, etc.) I can't get 3G data back until I pull the battery and restart the phone. The 3G icon doesn't even show along the top status bar. When I turn Wi-fi on from the power bar, I have data again but still no 3G... My dad has a Bionic too, and he has had the same issue with the data turning off during the day and he's also had problems with the phone not taking calls as well. I'm just wondering if anyone else is having these issues, and if you've found a way to fix it other than pulling the battery?
