It is less costly than the initial development, but not free. They may not feel it's worth it, or it could already be in the plans. The herald app only came out recently, it's possible an iPhone version will be optimized by the end of the month.
Think of designing a website for 800x600 and 1080p, but add in completely different usage environments as well and you'll get an idea of why you can't just straight port from one to the other.
And then do you develop for Android + Windows as well or just iOS? There's a lot of fragmentation which makes for difficult development work.
It's a big question for developers right now. Facebook, for example, has decided that they don't have the resources to dedicate to developing multiple apps which is why they're going to work to develop an improved mobile website experience for something like iPad (where you can't use chat right now).
