open web browser then return to game

Is there any way to open a remote web page from the app, then go back to the app?
The webpage needs to be pretty much full screen so will obscure the app.
would have thought that webpopup would have a close button, but it doesn't
and sometime clicking on links within a webpopup takes you to that page, and sometimes the web popup disappears.
if I use openurl, then the iphone or android buttons close the webpage and the app.

So how can I open a webpage from the app, allow the user to do something on the remote site, and then easily return to the app?
