IPhone – way to remove custom ringtones from an iPhone without using a Mac or PC

As far as I'm concerned (this has worked for my iPhone, and is covered in this guide as well), it works like this:

• In Import Settings, choose the AAC Encoder.
• Go to the library and right-click the song you want to use. Select Info, and then the Options tab.
• Here, set a time period using the Start and Stop markers. This period shouldn't exceed 40 seconds.

Now, let's convert it to the appropriate format.

• Click OK, and right-click the song again. Select "Create AAC Version".
• Locate the newly created AAC file ("Show in Finder" works on a Mac). It should reside in the same folder as the original, or in your iTunes library. Its extension will be .m4a.
• Rename the extension from m4a to m4r.

Clean up and re-import:

• Remove the AAC file from your iTunes library (do not move it to the Recycling Bin/Trash though)
• Re-import the m4r file by dragging it into iTunes
• Drag the newly imported file to your iPhone

iTunes movies

I have tested this with purchased movies from the iTunes Store.

It is not possible to change the artwork for purchased movies across devices using iCloud. The same is true for The movie title, summary, etc.

Changes to movie titles will be saved locally, even if you remove the download and download it at a later point in time. Other devices won't receive changed movie titles.

Movies without DRM

Movies without DRM that you have added yourself to your iTunes Library can be synced locally to your devices. Changes made to the artwork of these movie files will be updated upon the next sync (via USB/Wi-Fi).
