Why is it that Verizon, when I went to one of their stores, told me that they would take my Sprint iPhone 4S and make it work with their carrier? They said since I have a SIM slot, they could make it work. (The manager and two employees told me that at the store) And a AT&T employee also told me they could make my phone work with their carrier (but in this case it was a sort of kiosk store in the mall) But I see topics here saying it won't work... And yes my Sprint iPhone 4S was bought before 11/11/11 but I did restore it once. So are they lying to me or what? Thank you for the help.
