My device is not supported yet but it will be in the hopefully be in the future "iPhone 5s", A lot of people who is in the jailbreak scene have uploaded a TuT, for example EverythingApplePro & iCrackUriDevice and they have released for every jailbreak a TuT for a long time and they are trustworthy source "in my opinion", as ICrackUriDevice said in the video "this is a beta for the public & some tweaks might not work", they released a TuT because apple is still signing 10.2 and if something happens to your iPhone you can restore and still be on 10.2 and its a much stable Yalu version then the previous versions.
So for my opinion: I think you should do it because Apple is still signing 10.2 and if something happens you can restore and still be on 10.2, if they stop signing 10.2 then I think you should wait to jailbreak until qwertyoruiopz "Lucas Todesco" releases a much stable version for the jailbreak because its in beta at the moment.
