Untethered Jailbreak for iOS 10.3.1/iOS 10.3

Currently, there is not available any untethered or semi tethered solution for iOS 10.3.1 and iOS 10.3 versions.
However we can expect Keen Jailbreak solution for these versions. Cause KeenTeam already has proved iOS 11 jailbreak as well as iOS 10.3.2 jailbreak at MOSEC.
So, we can expect that KeenTeam will apply their jailbreak method for iOS 10.3.1 jailbreak, because of not having untethered jailbreak solution for iOS 10.3.1/ iOS 10.3 versions.
