Q: Do you know if any of the iPad accessories such as the photo adapter will work with the iPod touch?
Q: Will the iPad dock with keyboard work with the iPhone? If so I’ll get one right away.
A: Most of these accessories require support to be built into the device operating system itself, and at this time the iPhone OS version that is available for the iPhone and iPod touch do not support accessories such as the camera connector or keyboard.
It’s important to note that the iPad is expected to be running iPhone OS 3.2, a slightly newer version than is presently available for the iPhone and iPod touch. It’s therefore entirely possible that Apple could choose to provide support for these accessories in a future firmware release for the iPhone and iPod touch, but there are no guarantees that this will be the case.
Note that third-party software developers may also be able to support these accessories within their specific applications simply by accessing the Dock Connector or Bluetooth hardware directly, however it’s unclear whether Apple will release the necessary information required for developers to be able to easily support these accessories on the iPhone and iPod touch.
