"Canonical has confirmed that the first phone-friendly version of Ubuntu will be ready to launch when Ubuntu 13.10 goes live on October 17th.

Jolla Mobile's first Sailfish smartphone to ship by end of 2013 - Liliputing:
"Jolla Mobile is revealing a few more details about the company’s first smartphone, and the first device to ship with the Sailfish operating system... While it ships with the Linux-based Sailfish operating system, it’ll also be able to run Android apps. But we already knew that... The Sailfish operating system is an evolution of the MeeGo, a project to create a smartphone and tablet-friendly Linux operating system that was backed by Intel, Nokia, and others up until a few years ago."
"One of the things that has long separated desktop operating systems such as Windows and OS X from mobile platforms such as iOS and Android has been the ability to view multiple apps on a display at once.

Paranoid Android shifts gears, will focus on fewer devices - Liliputing:
"Paranoid Android is a custom version of Android that’s known for introducing unusual features such as custom touchscreen controls and a replacement for the notification and multitasking system in Google’s mobile operating system. Now the Paranoid Android team is laying out plans for their next release, and it looks like there will be a focus on building more things in-house, and ensuring solid support for a few devices rather than limited support for dozens. In other words, if you want to be certain you can run Paranoid Android once it’s based on Android 4.4, your best bet is to buy a Google Nexus device, although some others might be supported as well."
