Why are my network icons blue? Possible Duplicate:
  What does it mean when the connectivity icons in the status bar go white/gray?  




I've got a Motorola Electrify on Android 2.3. Sometimes my network icons (3G and the cellular network bars) are grey, and sometimes they're blue. They seem to be blue when I have a good connection and/or when my connection will work.

What exactly do the colors mean? I've noticed when I have a grey 3G icon, my wireless tether doesn't work at all and I often can't get web pages to load right, regardless of signal strength.
In my stock Ice Cream Sandwich, the icons turn blue when there is Internet connectivity and grey when there isn't. I'm not sure on Gingerbread though.
