i bought a iphone 4 but that person i bought a phone lost so ican not set up ...
How did the person you bought the iPhone 4 from lose and what does that have to do with you setting up the iPhone? On the other hand, if you're attempting to say that the person you purchased the iPhone from does not remove his iCloud passcode, let me bluntly say that there is NOTHING we can do for you. If that's not what you're saying, please be a bit more descriptive. Thanks.
