There was an earlier report of Apple going after the Samsung Galaxy Nexus for violating its slide to unlock patent, which left most Android users scratching their heads. It was obvious that the new unlock feature in Ice Cream Sandwich was vastly different than the traditional slide to unlock, leaving many to chalk this up to another Apple patent trolling.

In Sweden, international human rights and justice advocacy group Amnest International has launched a poignant advertising campaign called Slide to Unlock that uses custom iPhone and iPad wallpapers to try to raise awareness of the many innocent people wrongfully imprisoned around the world.

The campaign is as haunting as it is clever.
