Has anyone put the Mac Mail prog's new mail sound on their BlackBerry? I can't find them on my Mac... I think I did but they were aiffs.

Right click (control-click) the Mail application
Select "Show Package Contents"
Double click "Contents"
Double click "Resources"
Sort by "Kind"

You'll find 4 AIFF files titled: "Mail Fetch Error.aiff", "Mail Sent.aiff", "New Mail.aiff", and "No Mail.aiff"

Make sure you copy the files out of there rather than moving them (hold down Option key when dragging the files)
