I bought a 16GB Verizon iPad 3 refurbished from Apple's website. When I turn it on, I get a Verizon 3G signal - but I don't have an account, using it over WiFi right now. Would it say LTE or 4G if that service existed in my area? I am testing this with WiFi turned off. I've driven around to a couple places I might use it, like work - always says 3G. I'd like to know before I shell out $35 activation fee and $20 for service. If 3G is all I can get, then I'll try an AT&T model.
