FreeSync is a new tweak available in Cydia whose functionality boils down to offering the possibility to use our iDevice during a synchronization with iTunes. The tweak will display a pop-up when you start the synchronization and warn you that you can do absolutely anything on the terminal during this synchronization. The application developer warns users not to start the iPod application during synchronization in order not to corrupt the synchronization process and lose the songs. Although we are allowed to do anything during synchronization, do not forget that this synchronization complicates the way your device works.
FreeSync is available in Cydia for $0.99.
