How to unlock an iPhone from it's carrier?
I've recently got an iPhone from someone that was former on Sprints network. I'm trying to get the iPhone unlock so I can work on Virgin Mobile's carrier. I've spoke to them and they to be I would have to unlock the phone somehow and the company can take carry of the rest from downhill. Does anyone have or know I can unlock this phone without Jail breaking the phone or paying money to do this?
