I just received my replacement Droid 3 yesterday. Keep in mind this is my 3rd replacement phone in less than a year. This is the first phone where I can not seem to figure out why I cant connect to the Internet unless I am covered with a WiFi Hotspot. One thing I have noticed is the mobile signal strength bars does not have a 3G or 1x next to them like my last 2 phones did. I tried changing the Mobile Network from Global to CDMA but this didn't help either. Airplane mode is off and I can make calls and send receive texts just fine as well. Is there any other settings I need to change to have Internet access over the mobile network?
I depend on the internet on my Android device to stay connected so I definitely understand the importance of having access to your data. I appreciate the steps you've taken in trying to resolve this on your on. It sounds like you have checked all the right settings, so far.
I recognize the value in your time. Can you please this last step:
