Is it possible to tether this to a another device...i.e a rooted samsung galaxy s4?
I am not sure why you would need to. It has WiFi and 3G onboard... unless you mean the other way round, in which case YES you can by going into settings/wireless and networks
Foxfi should work.Well, The Verizon model is cheaper, I'm with AT&T and I don't want a 3G plan but I want to be able to tether it to my phone so that I can still get instant upload and all the benefits while I'm away from "Wifi"
