The main browser would be subject to the same security as any native app, so I'm not sure how the security issues would be any different than a native application.
because native applications are usually installed by choice.
With a browser the implication (of the poster) is you could browse anywhere. Which obviously is a security risk because any page you visit has access to the Iphone API.
Would you visit a site that had that kind of access in your desktop browser?
