Re: Best mp3 to iphone ringtone converter
You have to use MakeiPhoneRingtone application. MakeiPhoneRingtone is a quick drag and drop utility to turn AAC files into ringtones for your iPhone. Make ringtones from audio you already own, instead of purchasing it again and again. You can edit your file right in Fission and choose Save as iPhone Ringtone right in Fission’s File menu. To get this application click here.

I am using iPhone Ringtone Maker to convert mp3 files and I think you also use it. iPhone Ringtone Maker, a smart iPhone ringtone creator, can make your own ringtones from a wide range of video and audio files in your library and send the created ringtone to your iPhone 3G and all other models directly. What’s more, the iPhone ringtone converter can also edit video, trim audio and take music segment you like into your ringtone. It supports files like MP3, WMA, AAC, WAV, M4A, M4P, M4B.

I am using iRinger application for my apple iphone and it is very nice phone. I think you also use it. iRinger creates free ringtones for your iPhone (and iPhone 3G, 3GS) from virtually any music or video file you own. Even YouTube videos! iRinger exports ringtones to iTunes, so there is no need to “jailbreak” your iPhone. You will be creating ringtones in seconds. It’s that simple.
