WhatsApp is working on an option to react to messages with any emoji.

WhatsApp is bringing a feature that allows users to react to messages. It also allows them to view the reaction information.

Although there is still no 'dislike' option, you can definitely show your anger.

Reactions is a new Facebook feature that expands on the Like button and comes with six emoji that will allow users to express themselves more accurately.

Hacker geohot, AKA George Hotz -- best known for hacking the iPhone and Playstation 3 -- has developed a new photo sharing app that uses both the front and back cameras to capture both the subject and your reaction.
