I made some notchless wallpapers for the iPhone X. 
I still haven´t made my mind up on the notch thoug...How-to:

3D Touch the the pic you want, click on Share icon (Safari) save image to camera roll, go to settings, choose new background, pinch zoom out, set wallpaper to still. Sooo easy.

Thanks to NOTCHLESS.SPACE for the Photoshop template (go visit and download yourself)
