“The most useful voice command feature of the iPhone is the ability to make phone calls, particularly to contacts in your Address Book. This especially comes in handy when you must make a call while driving, or when you simply should not be distracted by having to look at the keyboard on your phone.”
I sure hope this feature isn’t common knowledge, otherwise I would feel stupid as hell for just founding out about it. This might have been forgotten with all the Siri hype of late, but seems a useful feature for iPhone 3GS and 4 owners. Phone calls, music commands…good stuff for the bootstrap iOwner.
