This reminds me of one of my pet peeves about the iOS UI - the date picker control. Yes, the scrolly spinners are a very cute UI and look awesome. But it'd be 10x faster if they'd just give me a number pad and let me hit the 8 digits rather than scroll up and down to get it just right.
I don't know of the specifics on this one, but in the UI/UX world it's rarely a good idea to "support both". They generally lead to bad looking UIs that "almost" work for everyone, but aren't a good fit for anyone.
