I think each phone has a different way of displaying it. While some of the phones will display 3G I think others will display the EV. I don't see why it would switch between the two on one handset. Ex. Your Admire has always shown 3G and not EV, but the Optimus M+ shows EV and not 3G. The HTC Wildfire shows EV as well, no 3G icon. 3G and EV is practically the same thing right? So why make two icons for it. I don't think there is such a "settling" in period, but if my phone ever switches from EV to 3G I will let the forums know.
