My 3g icon was gone with no data from 7pm till about 7am this morning. It finally came on when I got in my vehicle to go to work. I thought I was gonna have to flash stock image and if no good then get an exchange. My wife was sitting next to me all night with perfect 3g signal on her D3 so I thought it was my phone causing the issue. I was trying everything to get it to work toggling airplane mode, toggling data on/off, rebooting, and even reflashed my current rom after a cache/dalvik wipe and /system format.
