Software is needed that allows iphone users to convert mp3 files into ringtones and transfer these to the iphone. It should be possible to transfer any mp3 file on the hard disk to the iphone as ringtone.
The mp3 file can be chosen from the hard disk with a button in the software interface. The file can be played and listened to. By placing two markers, the beginning and end of the ringtone is determined. The file is transferred to the iphone by click of a button, and appears in the file of ringtones on the phone.
The software should have a modern look and be equipped with an installation and de-installation routine. Further the software should only function if a registration code is entered. This code should be created with a small tool.
