Rumors of iOS 5.1 including native Facebook integration first surfaced in January when iMore found a contact field for your Facebook ID within the contacts app in iOS 5.1 beta 3. Now, we have come across some more evidence that should confirm this rumor.

Thanks to some super sleuthing by the guys at Techie Buzz, they have noticed that updates being sent from the native iOS Facebook app once again show up as sent via ‘Facebook for iPhone’ or ”Facebook for iPad’, depending upon your device. If you remember, Facebook stopped showing this message a while back and would only show sent via ‘Mobile’, which is also what you see when you post an update through the Android app. This happened around the same time when Apple dropped Facebook sharing option from Ping.

But now it seems in preparation for the Facebook integration within iOS, Facebook has changed the way updates sent from the iOS app are being reported. And this is happening just a few hours before the iPad 3 event, where Apple is likely to also announce iOS 5.1. Meanwhile, updates sent from the Android app continue to be shown as sent via ‘Mobile’.

So it seems Apple and Facebook have finally put aside their differences and decided to work together. The Facebook integration should come as a welcome addition and will benefit everyone involved, the user, Apple as well as Facebook.

Nokia Lumia 800 users, here’s a reason to smile today – a new software update is available through Zune and it brings quite a punch. Marked with version number 1600.2487.8107.12070, the update brings new camera modes, better battery life and fixes backlight issues haunting some Lumia 800 owners.

The newly introduced camera modes are Smart group shot, Panorama, Action and Self Timer. Battery life also sees improvement, according to many users with already updated devices. Some of them also report a backlight issue being fixed by the firmware update.

According to some reports, currently only Lumia 800 owners in Singapore can benefit from the update, but a global release is imminent, so don’t be discouraged and try updating your device via Zune.

In a move that should surprise no one, Nokia will not be releasing the Nokia 808 PureView in the North American market. This information comes from Nokia’s developer website, which lists the availability of the 808 as ‘Global’, with a footnote than excludes North America.

Nokia has mentioned in the past that once their Windows Phone devices hit the North American market, they will no longer launch new Symbian and Series 40 handsets anymore. So all you North Americans out there who wish to get their hands on this 41-megapixel monster will just have to import it when the device hits the shelves everywhere else in the world.
