I need to know how to design new (different) user interface for iPhone with Photoshop or like that tools. I have already checked Photoshop design mockups for iPhone over the internet, but i'm sure, i don't need that, these example psd files shows original iPhone design elements.
I'm just looking to how to design new user interface and how to apply to iPhone application from kick-start. Let me give an example; I need to design new tab bar and apply to my small application as well as uiview, uiview background, modal uiview, buttons like that.
Unless you have a very good reason to replace the standard user interface elements, don't. Odds are, you will get them wrong and your application will look completely out-of-place on the device.
However, if you do want to test out mockups of your application interface, I recommend looking at Briefs, a new framework for prototyping iPhone applications. It lets you specify a series of images and how you would like to interact with them, and creates a working application from that. It's a very impressive framework for iPhone UI designers.
