Last month we gave you the news that OnePlus, the new start-up from former Oppo VP Peter Lau, was partnering with CyanogenMod, and today Peter announced that its first phone, the OnePlus One will be available for ‘under $400’. OnePlus was founded in December by Lau after he resigned from Oppo, creators of the Oppo N1– the first phone to ship with CyanogenMod out of the box. Peter promised with OnePlus to create ‘a perfect phone at a killer price’, and today’s announcement on Google+ handily addresses the second half of that promise.
