As the undisputed King of Internet Video, it’s kind of hard for YouTube to make any big changes without the public noticing, but over the last 10 days, YouTube has slowly rolled out a redesigned logo, first on its iOS and Android apps, and now to Twitter and Facebook as well.

The new logo ditches the old, thick, bubbly font that’s been in use since the company first started out in 2005, for a flatter, more simplified look that prominently features the YouTube Play button. Curiously, YouTube hasn’t rolled out the new logo to its website yet, nor announced any official changes, but now that it’s in the official YouTube apps, it looks like it’s safe to say this change will be permanent.

Here’s a higher-res version of the new logo:

The SwiftKey 4.2 update has landed on Google Play today, bringing SwiftKey Cloud out of beta. The new feature will backup and sync your personal language profile across all of your devices, automatically pull trending phrases from Twitter and other news sources, and it brings enhanced personalization.

Facebook is reportedly working on a brand new app that’ll be strictly for celebrities. The app will allow the famous to better interact with fans in the hope that more will be encouraged to use the social network for sharing. It’s currently in testing with a small group of famous people, according to sources familiar with the project.

Continuing its expansion at roughly the same pace as the known universe, Facebook has just announced that they have acquired Mobile Technologies, the developer of Jibbigo, a universal translator app for Android and iOS.

While Facebook mobile apps are terrible, they deserve due credit for bringing Chat Heads to mobile apps. Chat Heads is a floating window that will allow you to directly notify and reply you of any new messages from your friend on Facebook. Soon after Chat Heads was introduced, the idea was copied by many other apps and even an Android ROM – Paranoid Android.

CallHeads from developer maboe brings Chat Heads like incoming notifications for all your incoming calls, replacing that full screen intrusive notification.
