How to choose your own PS Vita lock screen

The Vita's backgrounds can be customised pretty easily, but you can also change the front lock screen of the handheld. First copy over your chosen picture to your Vita, or download it from the browser. Tap the Photos icon, tap the bottom right icon, tap All, pick the right photo you want as your lock screen.

Then, tap the bottom right ",,," button and choose Use as Start Screen. Voila, when you next use your Vita, that picture will be the first thing you see. Check out sites like DeviantArt and PSVitaWallpaper for some dedicated examples.
