Currently, I'm not eligible for an upgrade, but one of my family member is. Can I use my family members upgrade to get the iphone 4s? That family member currently has no data plan... and i know that when you order it... it will ask you to pick a data plan... So what do I do if it is possible to use my family member's upgrade? Basically, I want to use my family member's upgrade to get the iphone 4s, while that family member plans to continue to use their current phone with no data on it. Is this possible and what would be the procedures? Thanks for the help!
