I would like to buy a iphone 5 for sprint and I do not want a contract and I have no problem spending $800 on a phone as long as its not a contract. And I have been looking and I can buy a new sealed iphone 5 on ebay for around $600 for sprint. But my only question is can I activate it without siging the contract? Since I did buy the phone at a reduced price and not on a contract. I know on verizon I could do this as long as I have the equipment already I can do it without a contract. Is sprint the same? I currently have no service with sprint.
