Images purporting to show the OnePlus One have leaked, finally revealing the device that the company claims will be the "best smartphone ever" - but sales will be limited by a complex 'invite system'.

Days after revealing that its "perfect smartphone" with "flagship specs" will launch for under $500, OnePlus now says it will in fact cost far less - under $400 - but the device itself remains unseen.

The company that promised to launch the "perfect smartphone" says that its OnePlus One will feature the "best specs" along with CyanogenMod, and will be "more attractive than any phone on the market."
