Jolla's heavily teased launch day in Finland has already spilled some major news: pricing and specs for the first Sailfish OS handset. The phone seems to be called "The Other Half" -- or at least that's the working title for now -- and judging from Jolla's Facebook page it consists of a colorful plastic case, available in various shades including orange or green, which hooks onto the main chassis containing a 4.5-inch display (of unknown resolution), dual-core processor, microSD expansion with 16GB onboard, a "4G" modem, user replaceable battery and an 8MP rear camera. The chassis recognizes which case is attached and adapts the visual theme of the OS to match, creating "your other half, exactly as you want it to be."

Perhaps more usefully, the Sailfish operating system will also be Android app compliant out of the box, and we're currently on the ground in Helsinki trying to discover exactly how developers and users will be able to put that feature to work (while also chasing down the rest of the specs). Meanwhile, there's an emphatic video message from Jolla co-founder Marc Dillon after the break, seeking the world's assistance in taking the heritage of MeeGo into a new era.

Update: We now hear that the phone will simply be called the "Jolla."

Update #2: Jolla has just clarified that 4G means LTE. The display resolution has been vaguely described as "HD," which to our minds suggests 720p. Furthermore, it sounds like the way the "other half" interfaces with the main body of the device allows for much deeper functionality beyond just personalization. We've just added our own video tour with more information.
