Strange question here on the symbol activity on the Bionic. If I turn on wifi, I see the wifi connected symbol at the top of phone. I also see 4G as well as the network signal strength meter. On the OG Droid, when wifi connected symbol was on, the 3G would go off. So why does 4G symbol stay on with the Bionic when wifi is enabled and connected? Also, does the network signal meter/bars have anything to do with the 3G/4G data connection signal or that just the voice connection signal?
