MyTunesSync transfers and play (MP3) your ITunes (PC) music files to your iPhone (iPhone4S) via WiFi. Before you begin, you should have downloaded and installed the Windows PC application from: http://www.nif.ro/downloads/MyTunesSync/MyTunesSync.msi
That will run in taskbar of your PC and will show you firstly the Apple ITunes application found, will start run it, and finally will display the IP address of your PC. With the PC's side taskbar application and Apple ITunes running, you can start the iPhone application side. By one single button tap, the synchronization should start. All the downloaded song files are stored in the application folder and you can play them by the embeded custom MP3 player. Finally, you can delete all the downloaded song files by tap on the Reset button.
To prevent Windows Firewall blocking the PC application and the used port (4538), the installer (MyTnesSync.msi) will setup also your Windows Firewall by adding the network-aware application and the used port to the Windows Firewall Exceptions List automatically at install time and removing it at uninstall. So, after installed the PC application and before run it, make sure that the 4538 port is authorized and the application is registered in Windows Firewall.
The iPhone application autodetect the IP address of your PC. If no connection could be made, then you might have not installed the PC application or the PC application is not running in taskbar or the Windows Firewall still blocking the appplication and/or the communication port.
