I plan on buying an AT&T 4S on eBay, then have one of my friends who is on AT&T get the unlock for me (what a great friend!). Anyways, my question is rather trivial, but, after restoring and getting the unlock, does the Carrier info change from "AT&T 12.0" to "Carrier 12.0?" Or whatever number should be there? Again, very trivial, but I want all AT&T influence gone from the phone. Thanks in advance!
