For an iPhone user, the choice of ringtone may become a little complicated, especially for the person who is not willing to spend a huge amount of money at the iTunes store. From your existing collection of MP3s, it is possible to select and download your desired tone with the help of the open source software. The loop which you choose must be music. The loop should not be text and the process should not take longer than 30 seconds. This can be done through audio editors, for better syncronisation. The converters help in converting the sample MP3 ringtones to MP4 format. The renamers assist the further conversion to the M4r extension. The MP3 ringtone is now ready to rock your iPhone. Everything is now possible with the revolution in telephony.
