The listing, Apple iPad 30-pin Digital AV Adapter HDMI cable iPod iPhone has ended.
This is used. I used it one time for a presentation.
Payed $40 on Amazon last year.
Note: Apple says that it only works with certain products. To get the full effect of the mirroring you will need one of the products that are listed on their site, however I have used this successfully with a first gen iPad, iPhone 3G, iPhone 3Gs, iPhone 4S & iPod 2nd gen. The iPhone 4s has 100% mirroring, while the other devices only mirror videos and apps like YouTube.
Here is what Apple has to say about this item:
Product Information
Use the Apple Digital AV Adapter to mirror whatever’s on your iPad or iPhone 4S screen — apps, presentations, websites, and more — on your HDTV or HDMI-compatible display in up to 1080p HD (movies play at up to 720p). Watch slideshows and movies on the big screen in up to 720p by connecting your iPad, iPhone 4, or iPod touch (4th generation) to an HDTV or HDMI-compatible display. The Apple Digital AV Adapter routes digital audio to screens that support it. Connect the Apple Digital AV Adapter to your iPad, iPhone 4, iPhone 4S, or iPod touch (4th generation) via the 30-pin dock connector and to your HDMI-compatible display using an HDMI cable (sold separately). A second 30-pin connector built into the AV adapter lets you charge and sync your device while it’s connected to your HDMI-compatible display.
