In iPhone, when ever you click any iTunes link, then it redirects to App Store or iTunes Store to open that link. It is sometime annoying that, it leaves the current app and goes to that app. We cannot open the App Store link directly from source app but a new jailbreak allows you to do so.
QuickStore 2 by kinda is a new paid jailbreak tweak which opens the App Store link directly from the source app. When ever you click iTunes link from browser or any other App then that link opens in the app itself in the popup browser. You can download app from that window also. QuickStore 2 also gives an option to download purchased from Spotlight.
QuickStore2 is available in Cydia BigBoss repo for $0.99 and is compatible with iPhone, iPad and iPod running iOS 7. Do you like this Tweak?
