go Bluetooth for audio adaptors instead of making Apple richer
If you just want to transmit music to an audio device with a 30 pin iPhone holder in it, try one of these: a Wireless Bluetooth Music Receiver for Bose Sounddock/Beatbox/etc. (do a search in Amazon, there are cheaper ones but from shadier sellers)
It is basically a little Bluetooth receiver you plug in the 30 pin device.
You can even transmit iTunes to the device from you Mac, if you like.
Is it audiophile quality? No. Is it better than those crappy FM receivers for car audio from iPhone? Much, much more so. Is it as good as top of the line dedicated wireless headphones (non Bluetooth), no way. Is it as good as plugging the iPhone right into an RCA Y adaptor? Probably not but, close. Is it good enough for 95 percent of users? YES. Will it recharge your phone? No way! Can you recharge your phone with a cable while it transmit music to this gadget? Sure. Can you walk around the room with your iPhone while it plays? Yep.
