So I have a Xoom 3G and I only use Wi-Fi. Jelly Bean is coming out for the WiFi-only version and of course Verizon is going to make sure that the 3G/4G version doesn't get Jelly Bean till Key Lime Pie is out. So my questions are: Would the WiFi version work on my Xoom? If so, can I somehow spoof it to think it's a WiFi version to get the update and/or can I manually update to the WiFi Jelly Bean?
Yes, you should be able to install a wifi only rom manually, I`ve just gone to ICS with 3g and its great.
