Troubleshooting here: Just bought my Razr a few hours ago. Since then I've been playing with it pretty much nonstop, yet not once have I entered 4G. (At least, it constantly displays 3G in the notification bar). I know there is 4G here, I played with a display unit that had 4G, and I've other friends that have 4G. I checked the CMDA/LTE option under Mobile Networks, and I am using the LTE option......Any ideas what's up?
