Nice simple explanation - thanks.
I've tried turning off the mobile network when the WiFi is white and I can't get phone calls, so I assume voice doesn't go thru WiFi? Or does it under some circumstances? I'm with ATT on a BES thru my company. Running 184.108.40.2064 because my company will give me 7 kinds of crap for screwing up the phone with an "unofficial OS".
