I was very impressed with the speedy turnaround for my Xoom update to 4g as well as the unexpected free gift.
I got mine back yesterday and despite a couple of calls to Verizon, my 4g still won't activate.
I have the correct LTE / CDMA option selected. I've powered down and re-seated the SIM.
I'm currently awaiting another call-back from VZW.
Any suggestions please?
