We first took a look at Wallpaper Changer HD for BlackBerry 10 over a year ago and it's been popular ever since.
With us having limitations on how much we can customize our devices these days compared to times past when we had thousands of themes to choose from, Wallpaper Changer HD offers us as near as we can get, plus with some extra special features.
The developer, ShaoSoft, is kindly offering up 1500 free copies of the app, but as you know from past offers - you will need to be quick as these get snapped up at the speed of light - well almost!
To download Wallpaper Changer for free just follow these simple steps:
Jump into BlackBerry World
Pull down from the top bezel and tap 'Redeem'
Enter the code WCHD500CB and the price should change to free and you're good to go
Need a quick reminder of the app? Check out our original video but bear in mind that the app has been updated since this video was shot.
If you don't manage to get the app for free but still want to give it a go you'll be pleased to know that at the time of publication the app has 50% of it's price. You can grab it from the link below:
