Leave it to hacker community to introduce an entirely new interface convention to a closed consumer device that’s only a month old. A member over at cre.ations.net has done just that, by introducing a really impressive navigation scheme for the iPhone that looks like a blend of the OSX dock and the new “stacks” that will be coming with OS 10.5. As impressive an accomplishment as this is, it’s really only made necessary by the addition of other hacked applications and functionality adding to the total number of home-screen icons for the iPhone. What will be really interesting is over the devices life, how Apple will approach this problem if they start introducing their own additional applications, and if it will turn out similar to this hacked approach.
