Cell Phone Security Suggestion

What would happen, while traveling anywhere, you lost your cell phone and the screen was locked as it should be? If found by a good Samaritan, they could do nothing to get your phone back to you. Here is a suggestion I recently ran across.
Be sure that your cell phone is set to automatically lock after a certain amount of time.
Then - Create a word document with the following information:
*This phone belongs to:
John/Jane Doe
If found, please call:
Insert your home number or your partner's cell phone number here, or more than one number.
[Not your own cell phone number]
1-555-555-1212
Or please email:
johnDoe@youremail address
Then - take a picture of this word document with your cell phone and save it as your "Locked Screen Wallpaper."
Then - hopefully, should someone find your phone and they press the "Home" key, the Lock Screen Wallpaper will appear with the above information.
Then, hopefully, you can get your phone back if you are in the area, Or, hopefully, you can convince the finder to mail it to your home along with your assurance that you will reimburse them for the mailing plus a reward.
