I found an iphone 3 next to a river, maybe months after someone lost it, i'm attempting to contact the original owner (i can see his settings, email address, etc). It has no service so I'm assuming he contacted ATT or whoever about the loss, etc. I charged it up, the phone apparently needs a new screen (funny marks on it but is totally readable) and the app button doesn't work. If the original owner doesn't reply back or doesn't want it back, like if he got it replaced by insurance, I'm thinking of keeping it, replacing the complete front screen including the button, I'm thinking it's maybe $70 for that, diy... Do you think this would be worth it? Will I be able to buy a plan for this phone and get it activated? I can see the serial number in the settings screen. If this is all possible, is it still worth it? Would $70 buy me a used iphone anyway without all this work..?
