The OnePlus One has been shrouded in mystery on its journey to launch, but the phone is now out in the open and looking pretty sweet.

OnePlus isn't a widely-recognised name right now but its first handset is pretty damn impressive, going shoulder to shoulder with smartphone titans but at a more affordable price.

The 16GB version is available in "Silk White" for £229 ($299, about AU$322) and the 64GB in "Sandstone Gray" for £269 ($349, about AU$375).

But the CyanogenMod-based handset is also pretty impressive in the spec department.

It's rocking a 5.5-inch 1080p display with a 2.5GHz quad-core Qualcomm Snapdragon processor, 3GB of RAM, a 13-megapixel camera, 5-megapixel front-facing snapper and 4K video support.

Smashingly good

OnePlus has announced that 100 handsets will be available in the US from April 25 via its "Smash" promotion, which you can apply for via this site.

What is this, you ask? Basically, you can smash up your existing phone and in exchange you'll be given a brand new One handset for just $1.

An exact date for a wide release hasn't been confirmed yet, but we know it'll be available very soon.
