Can anyone please tell me if iModsign ipa's still work in 8.1.3? - I've just puchased a new iPad Air 2 and have put IOS 8.1.3 on it but the apps that I've resigned with iModsign no longer work and fail on install

I've been told that InstaSign also no longer works

Help!!

Edit: Just put my iPad back to IOS 8.1.2 and IModsign ipa's work fine..

Anyone know where I can get a fix for this, so I can upgrade to IOS 8.1.3?

Thanks in advance
