hi guys.. I've recently bought an iphone 4s (IOS 7.0.6, 64GB) and now it is jailbroken.. and im use tongbu cuz i tried alot of apps but its not worth .. Usually it shouldn't be any problem with installing the apps via tongbu but when i try, it always fails.. it just says Failed! I've tried a lot of apps from tongbu's own market for jailbroken or jailed idevices and also ipa files from other websites.. what should I do?! :(
