Don't think the process would be too different from designing a website. I'd probably spend quite some time wireframing though to make sure things work properly. Then to make it look pretty, a nice blend of the iphone UI and the brand stuff which shouldn't take too long. Don't see any reason to re-invent the wheel here, copying the iphone UI look is a good idea imo.
I've got some psd's and stuff with the iphone UI if you want?
