iOS 5 Sorting of list of playlists
Oh brother ... I just spent about an hour trying to figure this out myself. I had my playlists in a nice order before this enforced alpha sorting. I hope there will be an update that will allow for some better customization.

Good news is ... I did find one leading symbol that will push your faves to the top! Without looking too ugly! And the voice command lady doesn't pronounce it!

Here it is:   ª

... copy and paste!

It's a superscript 'a' used as an ordinal counter in spanish.
It'll sort as an 'a' but it's so tiny it doesn't look like much, at least on the ipod screen it's kinda just a speck.

eta: don't know about iDrive or how it might look in the car display
