Jolla on Monday unveiled the first smartphone designed to run a Meego-inspired operating system called Sailfish. The Finnish mobile handset company, comprised of ex-Nokia employees, believes the self-titled mobile device will be a strong candidate in the mid- to high-end smartphone market.

The handset, which features no buttons on the front panel, will ship with a 4.5-inch Estrada display, a dual-core processor of unknown origin or clock speed, 16GB of internal flash storage, a microSD card slot and an 8-megapixel rear shooter. There's also a front-facing camera and 4G LTE support in regions where the technology is available.

The phone features a two-tone removable back shell that Jolla calls The Other Half. Interestingly enough, the color scheme of the operating system changes when different colored backplates are installed. The panels will initially be available in teal, red and light green.

The Jolla is available for pre-order as of writing if you are the adventurous type and want to get your name on the list early. Those that pre-order will receive a voucher worth 100 euros that will be deducted from the price of the phone when it ships.

The Jolla smartphone is expected to go on sale in the fourth quarter for 399 euros ($513). It'll ship in Europe first before expanding to other countries, we're told.

The company is expected to release more information about the handset at a press event later today. We'll update this post with more information as it becomes available.
