I recently broke the the back of my iPhone 4s which voids the warrenty. My upgrade date is in August. I purchased a iPhone 5 on Ebay this week but haven't activated it as of yet. My question.... If I activate my iPhone 5 may I reactivate my 4S at my upgrade date and then get another iPhone (Perhaps the next version) for $200/300? Or does using the phone I purchased from ebay cancel my ability to upgrade. Please give thoughts and personal experiences.
Thank you...
