Just had a quick question regarding the capabilities of an iPhone.
To what extent can an iPhone connected to a dock control the external device that hosts the dock with an iPhone app ?
For example: Lets assume I have a radio which also has a dock to mount the iPhone. Will it be possible for me to create an iPhone app that can control the radios tuner?
Would be really really helpful if someone can clarify the extent to which an iPhone can control an external device through a dock!
Thank you in advance!!
