Just about every smart phone built in the past several years has a chip set that supports USB host capabilities. Almost none of the handset manufacturers have enabled this via hardware and firmware support, however. There is plenty of ability for smart phones to interface to external devices of all types if the defined interfaces would be used. Not sure why we need Apple's special interface and the overhead of their protocols over those interfaces. Let's standardize on well-known and useful interfaces and support them on all devices. (I know, Apple isn't about "open" and they will do what they want.)

This is good information. Unfortunately there are not a lot of smart phones other than iPhone that have interfaces that talk to simple microcontroller revealed(None of Android devices have that information published & Android SDK doesn't talk about it). And Apple doesn't open up hardware interface details to enthusiasts who are interested in developing products and obtain funding.
