Microsoft's budding mobile OS is finally learning to share, just like the big kids. Windows Phone's graduation to Mango comes not only with Twitter integration, SkyDrive music streaming, and multitasking, but with internet connection sharing as well. The new feature showed its toggle switch at WPCentral this week, riding in on a Microsoft flashed Focus running Mango build 7720.68. According to the tell-all image, Windows Phones running Mango will be able to share their cellular internet connection with up to 5 devices -- reportedly draining its battery with unprecedented efficiency. ChevronWP7 collaborator Rafael Rivera confirmed over Twitter that the feature is baked into Mango, guessing that it would require a "carrier 'update' to enable." Yeah, we wouldn't be surprised.
