Specifically, I'm trying to make a purchase inside a certain iPhone app using Paypal. Instead of the app opening for me a paypal url in the Safari, it seems to be loading the paypal url in a browser window inside the app. I can't see the url of the page and in general can't be sure that the app isn't intercepting my paypal credentials.
Is there a way to see what the url is of a browser window opened inside an app? Is there to verify that it is a genuine browser window and that the app can't eavesdrop on what I'm typing/submitting inside the window?
