Hi guys, while trying to hack Kingdom Rush Origins on my iPhone 4 7.1.2 JB, I ecountered a problem.You see, i installed the hack using AppCake, because neither iFunbox nor iFile would install it(I try to open it in iFile, app frezzes and .deb doesn't open and on iFunbox i tried to install it as an app but it fails).AppCake tells me it succesfully installed but after I respring nothing shows up in the settings.Yes, I installed PreferenceLoader.Please help! I'm starting to lose sanity.

Help!It wont't let me install it!(iFunbox or iFile)

Thanks, I was just wondering because when the first jailbreak for iOS 7.x.x came out it destroyed your calls and signal.

If I jailbreak will I still be able to call people, recieve calls, and will my carrier still be alright?
