So, I went to police station this morning and have my iphone back.
The police officer took a photo of my iphone with me, they said they need it to keep as a record. I really appreciated it. I also asked about the guy who stole my iphone. They said that someone found my iphone and returned it. So, there is no"theft". I have no idea why they explained it in this way. The moral of the story, someone stole my iphone and he would not be punished if he returned it to police. However, my iphone is back.
But unfortunately, my iphone cannot be turned on. It just stays on the pineapple screen. I think i need to use PwnageTool to reboot it. .
