If you’ve jailbroken your iPhone 4S with the Absinthe jailbreak, you might have run into the issue of having white icons on your home screen. The apps that turn white work as normal, but appear blank on the surface.
Here’s how to fix this bug:
- Respring your iPhone via SBSettings (it worked to fix one icon for me)
- Install any free app from Cydia (as recommended by @planetbeing; this worked)
If all else fails, re-jailbreak with the latest version of Absinthe v0.4, released yesterday. What fixes have worked for you to get rid of those blank icons?
