I can't get the App Store to open on my iPhone 4(6.1.2) I even restored it as the window for 6.1.2 is still open as I need to have an untethered jailbreak and even tried to reset all settings and network settings but without joy,and its the same on my iPad 3(6.1.2) AppStore won't open or iTunes in my iPad 3 so if anybody has a fix for this let me know please.
