If you found a smart phone, and it’s a T-Mobile G2 you may get a nice reward if its mine. The Stuffbak serrvice I signed up for does it for you. An info owner info label is attached on back of phone to ouside of battery cover. May require removal of the black plastic detachable Body Glove Case from the back of the phone.

Reward and shipping info will be provided free by calling 800-800-8257.
Better hurry, because I use Lookout Mobile Security https://www.mylookout.com/features/missing-device and it could start screaming for it’s owner to come find it at any time.
