Hey! Quick question... I am planning on buying the 5S soon, and am wondering if you could help me solve this upgrade question? My brother and I are together on the same account, he is eligible for an upgrade, but I am not until early next year. (He is ok with it, so no worries!) If I order the 5S online through his phone number, and then when the phone arrives swap the phone to my number. Will my upgrade (early next year) be given to him, or will his reset? Or, is there anyway to switch upgrades through Sprint before even buying the phone? Sorry if this is confusing, but I would appreciate you help. Thanks!
