Codes in the iOS 5.1 beta 3 firmware seeded to developers shows that Apple could plan introducing Facebook into the contacts, just as the current version does with Twitter.
Baked-in Facebook would give users the opportunity to post pictures and videos to their accounts directly from iOS, without having to open the Facebook app.
Tech site iMore was the first to discover the reference to Facebook in the iOS 5 beta late last week.
The team found that the operating system features a field for a Facebook user name in the contacts app and came up with a demonstrative screenshot.
As the caption shows, users can add info to their Facebook account in the same way they can currently add Twitter usernames.
However, this is pure speculation and it’s still uncertain if Apple will make the feature available, or even if they will release it one day.
