Personalize your device for free with Sticky4 for BlackBerry 10
Sticky4 is a free native BlackBerry 10 application that houses a bunch of wallpapers, themes, avatars and ringtones - all designed to give your BlackBerry some sweet personalization. With a user friendly interface, switching wallpapers etc doesn't get much easier than this.
Once you open up Sticky4 you'll be on the wallpaper page by default. When you find one you like the look of just give it a tap and a box will appear on-screen asking if you want to set it as your wallpaper. Tap yes and you're done - simple.
Jump into the menu and here you'll find the other features. Setting a new BBM avatar and theme is done in the same way as with the wallpapers. Ringtones are slightly different though. Once you tap on one you will again get a pop up box on-screen but it will ask if you want to download the sound. Tap the download tab and the ringtone will be saved to your SD card, so you'll need to jump into the folder to set it as your ringtone or as a notification. Within the pop-up box you will see a 'Play' icon so you can preview the sound before making the decision to download.
And that's about it. A free feature rich application which is available for all BlackBerry 10 devices. Grab it from the link below - you won't regret it.
