I know this is too late. :p
I tried searching for the psd but could not find a good one. So i decided to make myself one.
And here it is.
A pixel-perfect photoshop design in full scale. That means the screen actually covers 1280x720 px so that you can put your screenies without resizing it.
This is free for personal use.
Please give proper credits if you use it.
And don't post it somewhere else.
Click above image for High-Res preview.
For those who don't know what psd is:
It's a photoshop document.
You need Adobe photoshop to open this file.
You can use this file to show off your screenshots, mods, Roms etc.
Enjoy!
