I tried to find information about using OAuth (such as Twitter login) in S40 web apps, but couldn't find much. So: Does a published web app has some kind of default URL? I'd like to pass some callback URL for the OAuth authentication flow, so that after mwl.loadURL() and OAuth login activities the user could be redirected back to the web app (to pass authentication tokens)?

Or is it possible to accomplish some kind of "login manipulation" at the proxy side with widget.openURL()?

Or is the only possibility to use some PIN code login method such as https://dev.twitter.com/docs/auth#oob ?

Thanks for your time and help in advance!
