Those still hoping to get their hands on a OnePlus One invite now have yet another giveaway to enter. To celebrate the launch of its new SwapStyle cover, the Chinese firm has promised 5,000 invites to lucky winners who sign up and “perform at least one of the listed actions” by 6:15 a.m. PDT tomorrow, July 23.

You don’t have to have been an early OnePlus supporter to bag one of these invites; you could have decided you want the smartphone yesterday and you still have just as good a chance as everyone else at getting lucky. What’s more, entering the contest is incredibly easy — but it means spamming your friends on your favorite social networks.

To sign up, you need to visit the “Blizzard of Invites” page and log in with your email or Facebook account. You can also sign up via the OnePlus Facebook page, so if the contest site is down (which is has been frequently since the giveaway was announced) you can still enter.

You’ll then need to complete one of four tasks, which include liking OnePlus on Facebook, following the company on Twitter or Instagram, or contributing to the official OnePlus forum. Winners will then be selected at random when the contest ends tomorrow at 6:15 a.m. PDT. That’s 9:15 p.m. CST, 3:15 p.m. CET, and 9:15 a.m. EDT.

OnePlus says that the lucky winners will be informed within 72 hours, and 10 will also receive a free bamboo SwapStyle cover. So, what are you waiting for?
