Can I add personal info to my iPod touch's lock screen? My dad just got a new iPod Touch, and he'd like to add his personal info to the lock screen. If possible, how do I do this (without jailbreaking)?
The easiest way to go about this without jailbreaking is to use some custom wallpaper.

Make a new document in Photoshop, Pixelmator, GIMP, or your editor of choice.

Find a high-resolution image on the Web that you like and copy it into the document. Crop it to 640 x 960 pixels.

Add some text with your personal info over the image. Make sure that you leave ~225px space at the top of the image and ~150 at the bottom (these will be covered by the unlock UI). A subtle drop shadow can help make the text easier to read.
Export the image is a JPEG or PNG.



Use your preferred method to get the photo onto your iPod (sync with iTunes, email to yourself, Dropbox app, etc.).

On the iPod, go to Settings-> Wallpaper and select your custom image. You can set it as wallpaper for only the lock screen or the lock screen and home screen.

You'll now have custom text on the lock screen:
