Do you have GPS Today installed, by any chance? That app appears to connect periodically unless the option "Disable Data at All Times" is checked.
Regarding the tweak tools, I agree. My problem was corrected by a hard reset. In the end, anything could have caused the problem. I am not ready to blame it on Advanced Config or Diamond Tweak. Apparently, not everyone that has these tools installed has had a problem answering calls when the data connection is on.
