Hi Everyone, I purchased a launch day 5s for myself and used one of my account upgrades. I intend to return it and get one that better suits my wife (white and smaller memory size). Does anyone know how long after Apple receives the return that they reset the upgrade eligibility? Does anyone have any experience with this? I called Apple customer service and inquired but she "didn't know how that works" so I'm curious as to how it will work and worried that something may get messed up in doing so. Thoughts? Experiences? Thanks in advance!
