Hi, I have a Verizon iPhone 5 in which I unlocked to use on Tmobile (I had to pay to get it unlocked to Tmobile), and I have a couple questions.. So with the upcoming update of iOS 7, I've heard rumors that I would have to go through the whole unlocking procedure again if decide to update it when iOS 7 comes out.. Is that true? Another question I have is, I'm currently running on 3G on this iphone 5, is there ANY possible way to have it run on 4g or LTE? Thanks.
