Can I stop mobile Safari from opening my bookmarks whenever I start the app? Whenever I start Safari on my iPhone it insists on bringing up the last bookmarks folder I happened to be in. Is there a way to disable this behaviour and just have it present me with an empty page when I start up the app? I don't use bookmarks and the process of waiting for that bookmark view to show up and then dismissing it is surprisingly time consuming.

This is mobile Safari on iOS 4 running on an iPhone 3GS. The phone has not been jailbroken.
As of iOS 5.1 Mobile Safari no longer opens your bookmarks folder when you start it on your iPhone. It shows you the empty browser screen and you have to click on the bookmarks icon to bring up the bookmarks list.
