Hey Guys! Congrats to everyone who managed to get their Vigor so early. I have a noob question for you guys. I know next to nothing about the whole 4G LTE thing. I mean I know it's a faster speed as far as upload/downloads but how they work and what all you need to make it work I'm unsure of. The reason I'm asking is that I am planing on getting the Vigor and but I'm looking at flashing it to a different network. The thing is this network doesnt have 4G LTE capability so after watching the wirefly unboxing video I noticed that the guy doing it said he didn't have a LTE sim card for the phone so he didn't even know if it would work or not. That got me concerned so basically I'm wondering 2 things. How do you get the LTE sim cards for these phones and does a 4G LTE phone work on a 3G only network? As I said I'm sure this is a noob question but as the time for purchasing this gets closer I wont to be sure about what I'm getting into. Thanks in advance.
