First, get yourself an audio converter that can convert between m4a and mp3. (there are many free ones out there, try download.com)

Next, get yourself an audio editing software (ex. Audacity, again download.com)

Next, make sure you can change file extentions on your files. many ppl have already posted how to do this so i wont.

Next, find the song you want and open it in your audio editor and crop off approx 30sec of the part you like. If you have a good editor it will be able to export to m4a if not then just export your selection to mp3.

Next, convert the piece of your song that you exported from mp3 to m4a using the audio converter.

Next, rename the converted piece of your song so that its filename beguins with letters, no charachters or numbers, and change the file extention to m4r. your pc will automatically recognize it as a ringtone file type.

Next, if there's no Ringtones folder in your iTunes/Media folder then just create one make sure you spell it correctly, then put the file in there.

Next, open iTunes and make sure you SIGN OUT of iTunes Store (on the top menu bar of iTunes go to Store then Sign Out) once youre signed out drag and drop your file from the Ringtones folder into iTunes, anywhere in your Music Library screen, iTunes will recognize it as a ringtone.

Next, connect your phone, make sure you've selected Manually manage my music and videos on the bottom of the Summary screen. then go to the Ringtones tab and select your file and sync.

Next, without disconecting your phone from the pc, go into your phone and make sure you can see the ringtone in settings sounds rintones, it should be under custom. set it as a ringone and then eject your phone from you pc.

Next, drive by the Apple HQ while sticking a giant middle finger out the window and laughing b/c you can now have watever song you want as your ringtone for free. Its not enough that the iPhone and your plan/data usage charges, and your iTunes Store purchases cost so much, but you gotta pay to enjoy what you bought and is by all means entirely yours.

WOW! I tried and tried but could not figure out how to change formats!!! My screen looked NOTHING like the windows shown here. I found a website that explains it differently and it worked for me! Yayyyy!

Here's the link. Also, one step that is missing that unlocked the whole process for me was located in one of the comments… I'll copy and paste that first. Good luck! And I am pretty non-technical and brand new to itunes and I figured it out, so I'm sure you will too. :)

FIRST – Go to Control Panel………dbl click on Folder options……..click View tab………..uncheck “Hide extensions for known file types”………… (This allows you to see what kind of file it is and be able to change it).

Also, after step 10, just click and drag the clipped song onto your desktop. From there you can right click it and rename it changing only the end part. This is easier than doing steps 11-13.

Hope this helps some of you that were not being able to change it in Vista or with the new Itunes.
