From reading the official Kuaiyong website they have backtracked their operation.
It seems that the people behind Kuaiyong have had pressures brought against them from higher powers.
This is good news for developers on the iOS platform and that of people who are sworn against piracy.
I warned in an earlier post LINK that Kuaiyong was “dodgy” at best. At least now people will be less inclined to use such services and stay safe.
