Here’s a neat idea that will make you wonder why you hadn’t thought of this already. I know that’s what I thought as soon as I saw it.
Even though we have stuff like Find my iPhone and Find my Mac available, what about that honest person who finds your iPad or iPhone on a bus or in a restaurant and wants to return it to you? If you haven’t engraved your contact information onto the iPad (and who does that, really?), and you’ve set a passcode to get past the lock screen, that kind individual will be out of luck in trying to find you to get your iPad or iPhone back to you.
What’s a helpful iOS device owner to do, then, to help a good samaritan return a lost item?
Put your contact info in the lock screen image, of course! Here’s how.
Launch a drawing app on your iPad, iPhone, or iPod touch, and create a new drawing. I used Paper by FiftyThree for this example, because it’s pretty and stuff. Write the contact info you’d like someone to have if they want to return your device to you. If you’re not comfortable giving out a home address, try a work address, or phone number, or email/twitter account.
Save the image to your Photo Roll, and then open your Photos app. Tap the image you want to use as your lock screen information, and then hit the Share button in the upper right corner. Tap Use as Wallpaper, then tap Set Lock Screen.
That’s it. Now anyone who finds your device can contact you if they’re an honest person and can read your handwriting.
