I bought my 4S over a year ago and had an incident where I had to have it replaced through insurance. The one they sent me was unlocked (I'm assuming as I'm all somewhat new to this), and I was curious if there was a way to restore the Verizon setting in the network portion. I had backed it up from my previous one activated through Verizon, but I don't currently have any more of the backups available in iTunes. It still makes calls and receives texts, and I've done some googling trying to see if there was a carrier bundle, but I'm having no such luck. I've dialed the *228 activate it through over the air, but I'm not sure there's a way to force a carrier update or not. Can someone point me in the right direction? It basically just says "Not Available" under the Network settings but shows my carrier as "Verizon 14.0"
