I am currently using WMP 7.1 on my iPAQ 3650.
My only complaint is it doesn't seem to play WAV files recorded with
the voice memo recorder (is there a setting I can change?)

I am considering moving to WMP 9, because the current SDK on
microsoft's site is for 9. Will WMP 9 run on my iPAQ? (I am reluctant
to upgrade the OS to 2002 since in all regards the device functions
fine for my purposes.)

Any advice appreciated!
