App Language Switcher is a tweak launched last night in Cydia, and with its help we can change the language used in individual iOS applications. You all know that iOS was specially designed to display its elements in various languages around the world, some third-party applications have special interfaces for some languages, but the applications use the settings for the whole iOS. If you want iOS to have the English language set, but for certain applications to have the Romanian language set, then App Language Switcher can help you.
It can change the application language to something different than the system language. You can set language for installed apps in Settings > AppLangSwitch. Then you have to exit the app and open again to see the changes. Languages may not be changed for some apps like Cydia, iFile, FIFA 12 etc. Some apps like Mail, Messages, App Store, iTunes use Frameworks and Private Frameworks, so you have to set languages on those required frameworks as well.
The tweak has a settings menu in the Settings application of iOS, there you can specify the language used by the various applications installed in your terminals, and after reopening the application you will see it displayed. Unfortunately, the tweak does not work with all iOS applications, but at least it will work with the native ones for sure. App Language Switcher is available for $0.99 in Cydia's BigBoss repo.
