I feel confident about posting this first bug report because it is all over the XDA Forums, and I got hit with it myself. At some point, the "1x" and "3G" will disappear, signal bars will remain, and the phone will have no data connectivity. If you go to settings, you will see that data is "turning on" and the check box is grayed out. Current way to restore is to reboot the phone. Since many people are having this issue, I wanted to raise it here. Thanks for the great ROM!
