If the phone was lost or stolen, odds are the previous owner reported it. If so, then yes, this info is attached to the phone and you won't be able to re-activate it. Why not do the right thing? Call either the cell # or one of the frequently called contacts on the phone and let them know you found it. They may thank you with a reward or, if they have a new phone by now, they might remove the report and let you keep it. In any case, you get to feel good for playing the good guy. ;)
