By way of Ladyada comes this tidbit from this morning’s iPhone OS 3.0 press conference. She writes:
Ryan Block from GDGT has some major news from the iPhone 3.0 press conference, pretty soon you’ll be able to make/hack/add any accessories to the iPhone – wow! We’ll see some Arduino projects shortly.
10:20AM – Apps talk to accessories via the dock connector and via Bluetooth. Supports standard protocols (playing music, album artwork, etc.) and you can build custom protocols.
“With iPhone 3.0 we’re going to take this to the next level: we’re going to enable devs to build custom accessories that talk right to the iPhone.” This is exactly what people have been wanting. “You can give the iPhone an equalizer to a speaker system. Here’s another example: FM transmitter, which would find the optimal broadcast channel and play your music. Here’s another class we think will be interesting: medical devices.”
Oh, and in other iPhone OS announcement shockers: Cut, Copy, Paste! (finally) and Multimedia Messaging (ditto).
