Hi, I would like to get a friend's Verizon iPhone 4s unlocked as we are studying overseas and she would prefer to use that rather than one of the lousy Samsung galaxy peapod things they sell at Italy's Wind store (the carrier). I unlocked my phone, and a roommate's, through an unlock service on ebay for $5 but those were AT&T. I cannot find a similar service for Verizon and when I do it is much more expensive. What do I not understand about the Verizon variant? How can I go about doing this?
