I just sent another feedback form for this month. I'm really sick of this. It's not only frustrating that they broke the double-tap functionality, but that the iPod Touch and iPhone teams refuse to even comment or acknowledge our frustrations. They act like this is a free product or service and we should be happy with what we get, when everyone here paid a lot of good money for the device and even more for apps, music and movies to use on their iPhones and iPod Touches.
Please, if you haven't already, or haven't done so in over a week or two, send in a short, polite bit of feedback regarding this. They can only ignore an issue like this for so long.

I'm honestly surprised they've given us the cold shoulder for this long as it is.
