ikuti cara dibawah ini, dgn menggunakan SwapTunes sekarang iphone saya bisa sync di dua itunes: dirumah pake mac dan dikantor pake windows!
The newest third-party native application available through the Nullriver iPhone Installer (Installer.app) is SwapTunes.
This nifty little app basically allows you to store two separate music libraries on your iPhone - and lets you switch between the two libraries once they're loaded up on your iPhone.
SwapTunes is readily available through Installer.app on your iPhone. Find the SwapTunes.app under "Utilities" and click install.
Sync your iPhone with the first iTunes library (disconnect afterwards), then run the SwapTunes app from your iPhone, then sync with the second iTunes library, and then run SwapTunes to switch between your two media libraries. It's that simple!
