QuickStore is a jailbreak tweak that allows users to quickly open App Store links within apps. The tweak contains a simple kill switch located in the Settings app, but outside of that, it’s ready to go as soon as it’s installed.
When App Store links are tapped while within another app, i.e. from Safari, then a pop up window will load the App Store inside of the currently running app.
QuickStore is compatible with iOS 6, and is available free of charge from Cydia’s BigBoss repo. What do you think? Would you consider using it?
