On our account we have 5 phones (1 dummy phone, 2 Android Smart phones, and 2 iPhones 4's ) All have unlimited text and unlimited data except the dummy phone. My dad's phone has an upgrade available (he has unlimited text and data with an iPhone). If i were to transfer the upgrade eligibility from his number to the dummy number would that remove his unlimited data and text? I want to be able to upgrade the dummy phone to get an iPhone to replace my android but i want to keep unlimited data and text on all the phones that have it including mine.

Thanks

Tim
