There are very good demos show a fixed header on top & scrollable contents below in mobile Safari(see: cubiq.org/dropbox/iphonescroll.html & doctyper.com/stuff/iphone/fixed/). But if we also want to scale image around within lower part. How can we do this?
I found the solution with the help of code from Alex Gibson. But it's not smoothy as Safari does. I'll try to solve this performance problem.
