need help with iphone layout with fixed tabs and scrolling content

I am looking to develop a webpage specifically for viewing on an iPhone/mobile browsers. The layout would be something like this:

I would like the two tabs at the top to be fixed, i.e. they would always appear at the top of the viewport/screen, and the content in each tab to scroll (the height of the content in each tab would exceed the remaining available height, and so I would want this to scroll).

Ideally there would also be a transition on swi开发者_开发技巧tching tabs (perhaps a simple fade would work best with the graphics capability of the iPhone), though this is not essential.

I would be grateful for any advice in getting this set up,

Thanks,

Nick

Look into JQTouch it's a library that does nice animations similar to iPhone native OS.
