Nokia is planning to hold a special event on October 22nd. The Finnish smartphone maker revealed on Twitter today that it plans to announce "more innovation," with a mysterious save the date image. After originally planning to launch a 6-inch Lumia 1520 Windows Phone at a September event in New York City, The Verge understands Nokia has delayed and opted for an October unveiling. Nokia's save the date teaser doesn't reveal exactly where the company is holding the event, but the sand dunes indicate it might be a more exotic location than normal.

Nokia is also expected to launch a 10.1-inch Windows RT device shortly. Codenamed Sirius, the tablet includes LTE connectivity and a special battery-equipped keyboard cover. Nokia may choose to unveil and launch the tablet alongside its Lumia 1520. We've reached out to Nokia for more information on its October 22nd event, and we'll update you accordingly.
