Drag & Slide

Drag & Slide

Hi all,
I'm trying to realize a mobile webapp composed of 3 or for pages. For the navigation I'd like to get a "facebook app swipe style" meaning that when i swipe i don't directly go to the other page but i drag the page a little bit and when i release the page "slides" to the next one. Is there a way to do that? I tried hard to google it but coulnd't find a real method to do it...another problem is that one of the pages will have google maps in it...so i'd like to have a kind of footer in every page and use that as target for the event. Any suggestions?
Thank you!
ciao
