no thanks. i have a clear conscience and would like to keep it that way.
Give it to me, I will unlock it and ensure it gets to a rightful owner.
On a side note the last time I was in the Apple store, some guy that worked for Fido came in and said a customer forgot his iPhone 4s in the Fido store. He claimed he tried to contact the customer, and contact the customers contact list. No one claimed the phone for a week, so he got a new sim card and claimed the phone as his own. The Apple employees didn't seem to care to track down the owner.
