Guys, I need help, i found a 16 gb iPhone in a cab in Singapore 4 days ago. I was waiting for a call on the phone from the owner so i can give it back but havent heard from anyone. The iPhone has a AT&T chip, so my take is someone from America had left the phone. The phone has a 4 digit password protector so i cannot even get inside to find out whose phone it is. I with the phone have now flown back to India and dont know what to do..... Can any one help how i can bypass or open the phone ... maybe i will only use it or give it to my brother .... Let me know if anyone knows how to ..?
