Apple has begun to ship its iPad Camera Connection Kit to customers who pre-ordered the accessory. Unlike other Apple iPad accessories, the Camera Connection Kit wasn’t available for pre-order until March 29, and was listed as shipping in “late April;” a shipment notification received by iLounge claims the dongle set will arrive by April 22. The iPad Camera Connection Kit includes two separate 30-pin connectors, one with an SD card slot, and the other with a USB port that can be used to attach most digital cameras. A recent report claimed that the USB-to-iPad connector may also provide support for USB audio devices, although this has yet to be confirmed.
