NOTE : I just want to backup only the data associated with Shazam app, not the full iPhone backup.
Apple recently swapped my iPhone 3GS due to some issues on the speaker, but I am having issues with 3G and WiFi after the swap. When I go and visited the Genius Bar, he suggested to restore the iPhone and set it up as a New iPhone, and not to restore via a backup copy of iPhone.
But the real problem is all the existing data is lost when I do this. So I want to take a backup of Shazam app and when I setup new iPhone, I can put this data back into the app.
How can I do this ?
