Since my update to KK I noticed that the 3G/4G signal grays out while wifi is on but while I was on Jellybean the indicator would completely go away. Does this mean my data is still being used? I ran across this on JB after I had signed up for the Verizon caller ID thing I disabled that as soon as I updated to KK. I looked around in the icon glossary and did a small search but didnt have any luck.
