Hello! everybody ,i need some help from you guys in the community , my wife will receive her upgraded iphone 4s today ,our plan is to sell it on ebay ,and then buy an unlocked iphone for full price when it will become available on Nov. since we travel often and need the full unlocked phone . My question is , how do i deal with the microsim that i think will be included in the phone ,can i activate it in november on the unlocked phone ,or i need to activate it right away with the phone that we will get on friday ? One more question if we sell the phone without the sim included will the buyer be able to activate the phone with his sim ?or it needs to be activated and then sold ? Any help would be greately appreciated.Thank you all !!
