Verizon consumer help ?

Ok so I found a droid in the mall in a girls bathroom. So I look around to see if the owner was still there but I was the only one. So then i had to leave to go home and I kept it for 2 yrs, and I know about the esn so, I was woundering like I hard reset it and I wanted to know if I can activate it cuz I have a blackberry curve from verizon ?? Sorry for the length
