Graph Search aims to help users find people, photos, places, and interests using data from their social network. It was unveiled in January and more information about it can be found here. Graph Search will reportedly be incorporated into the app's main search bar.
Additionally, Facebook is said to be working on a redesign of the Facebook Messenger app. Apparently, two designs are being tested.
The first version is said to look largely similar to the Messages application bundled into iOS. That version includes green interface elements. The second version in testing, which the source says is more likely to ship to end-users, is heavy on white space and very fitting for iOS 7′s design. It is not filled with blue interface elements like the new Facebook app. The new app has tabs for active/recent chats, contacts, and settings across the bottom…
The new Messenger app will also be able to access your Address Book to find users that can be contacted via the app. Its new icon is said to feature a blue chat bubble with a white border. Android users will also get similarly redesigned version of the app.
Facebook is also rumored to be testing new video filters for Instagram, but when or if those will be released is unclear.
Finally, Greg Novick, the lead engineer in charge of rebuilding Facebook's app and a former Apple employee responsible for the design of the original iPhone software, is said to be returning to Cupertino. The site hypothesizes that perhaps Novick will be working on the interface for Apple's rumored wearable devices.
