I must be confused as to whether or not this will work. to my understanding i should be able to play my iPhone music over my airport express connected to my home stereo. i have an 8011.N express on 7.4.2, and upgraded my phone to 4.2.1. still a no go. if i have to have an Apple TV to get this to function this is a big FAIL in my opinion. can anybody shed some light on this for me?
