Sometimes, not always, when I try to access data over the 3G network, I discover that the "Data Enabled" setting is not checked. If I go under settings and check it, all works as it should. I can't figure out, though, what is turning it off. I suspect it is happening when I have WiFi enabled and move to an area where WiFi is not available. Normally, the 3G connection automatically turns on, but as I said, not always. Does anyone have an idea what might be causing this strange behavior, and more importantly, what I can do to eliminate it? I am running Green Power and Juice Defender, so it's possible a setting there might be relevant, though I don't know what. Hope you can solve this minor irritation.
