There doesn't seem to be a way to turn off the Facebook Chat Head feature on iOS devices. You can turn of the Chat option, but this does not solve the problem, and it blocks your friends from being able to send you personal messages. The chat head bubbles will also still pop up when you access your Message screen.

To turn off Chat, swipe left to open the Chat screen, tap the icon at the top right of the display, and select "Turn Of Chat". Remember, this will not put and end to those little annoying heads cluttering up your display.

Facebook has released a major update to its iOS app, bringing several improvements to the iPhone and iPad. Chat Heads is one addition that has been adapted from Facebook Home on Android devices, which provides chat bubbles to help keep you in touch with friends from anywhere in the app. Other major changes have also been implemented in the latest Facebook.

Stickers make sending messages more fun, making it possible to send a variety of graphics and emoticons. Many stickers are free, however there are also stickers that can be purchased directly through the app. Another major change is a redesign of the news feed, with a cleaner layout and larger text.

Facebook today unveiled what CEO Mark Zuckerberg called the "next version" of the social networking site. Facebook Home is a new UI for Android devices that transforms a user's smartphone or tablet into a central hub for Facebook. When asked if Home will also be available for iOS devices Zuckerberg replied, “Apple is a very controlled environment". Meaning you will probably never see Home on your iPhone or iPad.

The Home interface is just too invasive for Apple's closed ecosystem. When installed, it takes over a device's lock screen, home screen and even notifications. This is something Apple would never allow. Zuckerberg said, Facebook has "great relationship with Apple", but that doesn't mean they will welcome a UI that overrides iOS. It's just not the way Apple does things.

Facebook has been working hard on its iOS app, with several updates launching recently. The latest free update hit the App Store on February 22. Most visible are new sharing buttons, which are simpler to use and provide an easier way to like, share and comment.

Free in-app calling is now officially a part of the Facebook app for iOS, making it possible to call your friends in the US and Canada without using voice plan minutes. The feature will of course use up some of your data plan as these calls are placed over the Internet.

We already pointed out in December that iOS devices seem to be running more Google apps than any other apps available in the App Store. So it makes sense that five of the top six mobile apps In 2012 were made by the search engine giant. Apple's decision to replace Google Maps on iOS 6 is the only reason why Facebook managed to nab the number one spot in 2012, according to the latest comScore Mobile Metrix ranking. Other apps rounding out the chart include Pandora, iTunes, Cooliris and Yahoo! Messenger.

Facebook also dominated in app usage accounting for 23% of time spent on apps. Facebook's redesigned app, which was much faster and user friendly, probably helped with usage. Facebook's sister app Instagram nabbed 3% of the market, while Gmail was the most used Google app. Various Google apps also accounted for 10% of app usage, making Facebook and Google products the most used on mobile devices in 2012.

To use the free voice calling feature on the Facebook Messenger app, just tap the "i" icon in the top right hand corner while viewing a chat with the person you want to call. Then select the "Free Call" option. You need to have the free Facebook Messenger app installed, a Facebook account and be connected to Wi-Fi for the feature to work

Facebook has begun rolling out its free voice call service to U.S. iPhone users. The free voice calling feature was originally tested in Canada, but now iPhone users in the U.S. with the Facebook Messenger app can also use the service.

To make a free voice call from the Facebook Messenger app, just tap the "i" icon in the top right hand corner while viewing a chat with the person you want to call. You will be taken to the "Contact Info" screen that now features the "Free Call" option. The calls can only be made over a Wi-Fi connection, so don't expect to use it while on the road.

Facebook is now getting a slice of the Apple iTunes gift card business. A new addition to Facebook Gifts is the ability to purchase digital gift cards good for purchasing music, movies, apps and more on the iTunes store. Buying one of these iTunes gifts simply involves logging into Facebook, charging the gift to your credit card and sending it to a Facebook friend.

How much easier could it be to shop for the holidays? Facebook now has over one billion users every month, and the site is looking for new ways to increase profits. Apple's iTunes gift card business clocks around $2 billion per year. Could Facebook Gifts and iTunes be a match made in heaven?

Version 5.0 of the iPhone and iPad Facebook app has finally landed in the app store! Facebook has rebuilt the app from the ground up making it much faster. The app now launches immediately and the news feed and photos load a lot more quickly.

The new app allows you to easily scroll through your news feed without having to refresh, and now features notification banners for recent posts. The app doesn't look any different, but you will immediately feel the changes the first time you use it. Facebook did not add the must asked for "Share" button featured on the web version.

Facebook has launched a new mobile feature called Find Friends Nearby (previously named Friendshake) for iOS and Android devices. Users who navigate to http://fb.com/ffn using their phone's browser will be shown a list of other users within a certain radius who are also using the page. You can also access the feature from the Facebook iOS app by going to Menu > Apps > Find friends > Other Tools > Find Friends Nearby.

Find Friends Nearby allows you to easily add people you've just met in real life. Say you meet someone at a party. You can both access the Find Friends Nearby page, locate each other, then add each other as friends on Facebook. This saves you the hassle of using Facebook's search or having to spell out your email or name. I guess it can also be used like Chatroulette to meet new people.
