I have a coworker with a Sprint Sanyo SCP8500 Katan Delux. It was unlocked in a store and is being used on Metro now. Today it got locked and they don't have the unlock code. I recommended to try last 4 of SSN, the last 4 of it's current and previous phone numbers, 0000, 1111, etc and it didn't work. Does anyone have any ideas on what the code might be, or on a way to bypass it?
