If I may:
Daffie, that repo you are using for FakeClockUp is a repo for mainly piracy and pirates. It is NOT a repo on which this forum allows any discussion. Per our rules, any discussion of piracy and related repos, tweaks and apps may lead to removal of posting privileges.
That's what f4780y means when he [oh-so-gently] suggested you (1) read the rules and (2) remove that repo from your iPad.
The good news is that there is a perfectly legit repo for the FakeClockUp tweak:
http://hitoriblog.com/apt/. Just add that repo (and delete the bad one). You'll be good to go and you'll not run the risk of having a bad repo on your device.
