When I connect to Wifi, the 4G icon doesn't disappear like the 3G icon did when I connected to Wifi on my Droid. Does that mean the Razr is still using 4G data? I could go into Wifi settings and disable mobile data, which made the icon go away (and didn't affect the Wifi icon), but I don't want to have to do this everytime. I don't want it falling back on 4G while I'm connected to Wifi if something isn't processed when it expects it to.
