You still need an invitation to buy the OnePlus One or as its sometimes knows as "The One" - high self praise indeed. But if you are not keen on waiting for an invite you now have an alternative.....
The OnePlus One has recently come available for purchase through the OppoMart....hoorraaaahhh
The retailer has the 16GB Silk White version is available as of today, however there is a catch.
The OnePlus One (shipped through OnePlus) will be running a customized version of CyanogenMod, a kinda bastardised version UI thats ala Sony UI skin. But in the case of the model you will be purchasing through OppoMart -- you will be getting a OnePlus One with "Color OS"
It does contain the Google apps and love we come to expect with Android however there are a few bumps with the build in software, apparently according to a few devs on XDA its a bit buggy in places. Its worth pointing out its very easy to move over to full CM when its ready.
When we get our hands on one we will give it a proper review.
