Download Over Cellular? I have set up several alarms that use songs on my iPhone (iOS 6).

Whenever I modify one of those alarms (or create a new one with the now default setting of one of those songs) the phone asks me

Download Over Cellular?
Additional fees may apply when downloading songs over cellular.
(Cancel) (Download)


What does it want to download? The songs are on the phone.
Try:

Settings->General->Cellular scroll down and set

Use Cellular Data for: iTunes = ON

This doesn't mean it's going to re-download anything for the alarm, just gets rid of the stupid warning.

Also you can check
Settings->Itunes &amp; App Stores
Use Cellular Data = ON

If that doesn't make it go away, try resyncing library with itunes also.
