I want to unlock my iphone 5, because I've never done it before and want to try it out. I am just wondering what I need to do after getting it unlocked via ATT, or ebay. Do i get a verizon sim somehow? I wouldnt even know how to go about doing that, and then, would i have to activate that sim card? I'm sorry if this is a repost, but, i've read through the forums and cant find exactly what im asking.
