Another Ubuntu phone, another unusual launch. After the BQ Aquaris E4.5, which debuted with a series of online flash sales, Canonical is following up with an invite-only handset built by Meizu. Yep, the same Meizu that once hoped to release an Ubuntu phone in 2014. The new MX4 "Ubuntu Edition" has been available to developers in China since May, but starting tomorrow you'll be able to order one in Europe too. At least, you will if you're lucky enough to receive an invite. Canonical and Meizu aren't revealing how many will be available each day, so you'll just have to visit their teaser site, complete the "origami wall" and hope for the best. The company is also staying tight-lipped about whether the invite system will eventually be dropped and if the MX4 will later be sold in other markets.
