I don't think there is one for 10.2.1 ATM
There is one for 10.2.0 Though
Just have to wait and camp on some websites like Pangu and Taig,
And as far as i know any tutorials that tell you to go to a webpage and save the icon are gimmicks, you need to have some external software to do a proper jailbreak.
And if there is a semi-tethered JB Out for 10.2.1 then you can try it out.
It basically means that if you restart your iPhone it will default back to its Non-JB State.
