No those are fake, what we are all waiting for is pangu to release its much anticipated ios 10.3.1 maybe ios 10.3.2 jailbreak, nick named "janus" we were waiting for ios 10.3.2 to be released before the tool was and now its just sitting and waiting hoping they dont sell out, but if they do we need to understand. They do have a company to maintain. /: hopefully they continue to release jailbreaks though
