HI ,

Recently i bought a used iphone 4s . i checked only that it's unlocked for all netwoeks before i bought .

just before handingh over to me the seller did a factory reset of the phone and i left without checking it further.later it's asking apple id and password to os boot.e

un fortunately i left the place because my project exit and i supposed to move to back.

so how can i resolve this issue. i could not able to contact owner.??

i only know its IMEI number .. is it possible to do something from this IMEI number to have this phone working further.?
