After iOS 5 install, only some purchased ringtone transfer to iPhone After install of iOS 5 on my iPhone 4, I noticed that only 2 of my ringtones installed. I resynched. I explicitly requested a sync of my 7 purchased ringtones. Same result: iTunes synced the same 2 of 7.
I'm on OS X 10.6.8.

How can transfer all of my ringtones to my phone?
Similar thing was reported on Apple's forum (don't have the reference handy).  One guy said he fixed it by: deselect all ringtones, sync, select again, sync.  Another guy said he fixed it by downloading a single new ringtone.
